Мой путь:
Σ1..n = n(n+1)/2
OK
Подставляем в формулу 2n вместо n
Σ1..2n = 2n(2n+1)/2 = n(2n+1)

а действует ли этот путь для 3n?

Как это можно БЫСТРО высчитать? Надо сидеть считать (102,105...), или сумма всех цифр должно быть делимо на 3 или есть какой-то другой метод?

ОК, быстрый метод.
Как известно число делится на 3 когда сумма цифр числа делится на 3. К примеру 102 делится, т.к. 1+0+2=3, а 3 делится 3 само собой. Ближайшая к 200 (снизу) цифра 198, т.к. 1+9+8=18, далее 1+8=9, а 9 делится на 3 (=3 если что ).
Имеем ряд 102, 105... 198. А сколько их там в ряду ?
запишем ряд таким образом 99 + n*3, где n - целое положительное, т.е от 1 до ..."?"
Пусть 99+x*3=198
Решаем в лоб получаем 33. Таким образом n меняется от 1 до 33. Ответ - 33

Для Kasatka, чтобы не скучала (из RC1000).

Opponents of compulsory national service claim that such a program is not in keeping with the liberal principles upon which Western democracies are founded. This reasoning is reminiscent of the argument that a tax on one’s income is undemocratic because it violates one’s right to property. Such conceptions of the liberal state fail to take into account the intricate character of the social agreement that undergirds our liberties. It is only in the context of a community that the notion of individual rights has any application; individual rights are meant to define the limits of people’s actions with respect to other people. Implicit in such a context is the concept of shared sacrifice. Were no taxes paid, there could be no law enforcement, and the enforcement of law is of benefit to everyone in society. Thus, each of us must bear a share of the burden to ensure that the community is protected.
The responsibility to defend one’s nation against outside aggression is surely no less than the responsibility to help pay for law enforcement within the nation. Therefore, the state is certainly within its rights to compel citizens to perform national service when it is needed for the benefit of society.
It might be objected that the cases of taxation and national service are not analogous: While taxation must be coerced, the military is quite able to find recruits without resorting to conscription. Furthermore, proponents of national service do not limit its scope to only those duties absolutely necessary to the defense of the nation. Therefore, it may be contended, compulsory national service oversteps the acceptable boundaries of governmental interference in the lives of its citizens.
By responding thus, the opponent of national service has already allowed that it is a right of government to demand service when it is needed. But what is the true scope of the term “need”? If it is granted, say, that present tax policies are legitimate intrusions on the right to property, then it must also be granted that need involves more than just what is necessary for a sound national defense. Even the most conservative of politicians admits that tax money is rightly spent on programs that, while not necessary for the survival of the state, are nevertheless of great benefit to society. Can the opponent of national service truly claim that activities of the military such as quelling civil disorders, rebuilding dams and bridges, or assisting the victims of natural disasters—all extraneous to the defense of society against outside aggression—do not provide a similar benefit to the nation? Upon reflection, opponents of national service must concede that such a broadened conception of what is necessary is in keeping with the ideas of shared sacrifice and community benefit that are essential to the functioning of a liberal democratic state.

3. Which one of the following most accurately characterizes what the author means by the term “social agreement” (line 8)?

(С) an agreement among members of a community that they will petition the government for redress when government actions limit their rights
(D) an agreement between citizens and their government detailing which government actions do or do not infringe upon citizen’s personal freedoms
(E) an agreement between citizens and their government stating that the government has right to suspend individual liberties whenever it sees fit

4. According to the author, national service and taxation are analogous in the sense that both
(A) do not require that citizens be compelled to help bring them about
(B) are at odds with the notion of individual rights in a democracy
(С) require different degrees of sacrifice from different citizens
(D) allow the government to overstep its boundaries and interfere in the lives of citizens
(E) serve ends beyond those related to the basic survival of the state

5. Based on the information in the passage, which one of the following would most likely be found objectionable by those who oppose compulsory national service?
(A) the use of tax revenues to prevent the theft of national secrets by foreign agents
(B) the use of tax revenues to fund relief efforts for victims of natural disasters in other nations
(С) the use of tax revenues to support the upkeep of the nation’s standing army
(D) the use of tax revenues to fund programs for the maintenance of domestic dams and bridges
(E) the use of tax revenues to aid citizens who are victims of natural disasters

Решаем в лоб получаем 33. Таким образом n меняется от 1 до 33. Ответ - 33

Хочу заметить, что взято от 1, а не от нуля намеренно, т.к. если от 0, то ряд n = {0;1...32}
в таком случае можно в запарке прийти к выводу, что ответ 32, а это не так, т.к. забыли учесть 0, а это грубая ошибка. Если есть сомнения, то можно на бумаге или в уме решить более простую задачу, к примеру от 0 до 10 на тех же условиях для проверки метода.

Ну и в догонку RC#2

James Porter (1905-1970) was the first scholar to identify the African influence on visual art in the Americans, and much of what is known about the cultural legacy that African-American artists inherited from their African forebears has come to us by way of his work. Porter, a painter and art historian, began by studying African-American crafts of the eighteenth and nineteenth centuries. This research revealed that many of the household items created by African-American men and women—walking sticks, jugs, and textiles—displayed characteristics that linked them iconographically to artifacts of West Africa. Porter then went on to establish clearly the range of the cultural territory inherited by later African-American artists.
An example of this aspect of Porter’s research occurs in his essay “Robert S. Duncanson, Midwestern Romantic-Realist.” The work of Duncanson, a nineteenth-century painter of the Hudson River school, like that of his predecessor in the movement, Joshua Johnston, was commonly thought to have been created by a Euro-American artist. Porter proved definitively that both Duncanson and Johnston were of African ancestry. Porter published this finding and thousands of others in a comprehensive volume tracing the history of African-American art. At the time of its first printing in 1943, only two other books devoted exclusively to the accomplishments of African-American artists existed. Both of these books were written by Alain LeRoy Locke, a professor at the university where Porter also taught. While these earlier studies by Locke are interesting for being the first to survey the field, neither addressed the critical issue of African precursors; Porter’s book addressed this issue, painstakingly integrating the history of African-American art into the larger history of art in the Americas without separating it from those qualities that gave it its unique ties to African artisanship. Porter may have been especially attuned to these ties because of his conscious effort to maintain them in his own paintings, many of which combine the style of the genre portrait with evidence of an extensive knowledge of the cultural history of various African peoples.
In his later years, Porter wrote additional chapters for later editions of his book, constantly revising and correcting his findings, some of which had been based of necessity on fragmentary evidence. Among his later achievements were his definitive reckoning of the birth year of the painter Patrick Reason, long a point of scholarly uncertainty, and his identification of an unmarked grave in San Francisco as that of the sculptor Edmonia Lewis. At his death, Porter left extensive notes for unfinished project aimed at exploring the influence of African art on the art of the Western world generally, a body of research whose riches scholars still have not exhausted.


6. Which one of the following most accurately states the main idea of the passage?
(A) Because the connections between African-American art and other art in the Americas had been established by earlier scholars, Porter’s work focused on showing African-American art’s connections to African artisanship.
(B) In addition to showing the connections between African-American art and African artisanship, Porter’s most important achievement was illustrating the links between African-American art and other art in Americas.
(С) Despite the fact that his last book remains unfinished, Porter’s work was the first to devote its attention exclusively to the accomplishments of African-American artists.
(D) Although showing the connections between African-American art and African artisanship, Porter’s work concentrated primarily on placing African-American art in the context of Western art in general.
(E) While not the first body of scholarship to treat the subject of African-American art, Porter’s work was the first to show the connections between African-American art and African artisanship.

7. The discussion of Locke’s books is intended primarily to
(A) argue that Porte’s book depended upon Locke’s pioneering scholarship

(B) It was revised and improved upon in later editions.
(С) It took issue with several of Locke’s conclusions.
(D) It is considered the definitive version of Porter’s work.
(E) It explored the influence of African art on western art in general.

9. Given the information in the passage, Porter’s identification of the ancestry of Duncanson and Johnston provides conclusive evidence for which one of the following statements?
(A) Some of the characteristics defining the Hudson River school are iconographically linked to Weston African artisanship.
(B) Some of the works of Duncanson and Johnston are not in the style of the Hudson River school.
(С) Some of the work of Euro-American painters displays similarities to African-American crafts of the eighteenth and nineteenth centuries.
(D) Some of the works of the Hudson River school were done by African-American painters.
(E) Some of the works of Duncanson and Johnston were influenced by West African artifacts.

10. Which one of the following can most reasonably be inferred from the passage about the study that Porter left unfinished at his death?
(A) If completed, it would have contradicted some of the conclusions contained in his earlier book.
(B) If completed, it would have amended some of the conclusions contained in his earlier book.
(С) If completed, it would have brought up to date the comprehensive history of African-American art begun in his earlier book.
(D) If completed, it would have expanded upon the project of his earlier book by broadening the scope of inquiry found in the earlier book.
(E) If completed, it would have supported some of the theories put forth by Porter’s contemporaries since the publication of his earlier book.

11. Which of the following hypothetical observations is most closely analogous to the discoveries Porter made about African-American crafts of the eighteenth and nineteenth centuries?
(A) Contemporary Haitian social customs have a unique character dependent on but different from both their African and French origins.
(B) Popular music in the United States, some of which is based on African musical traditions, often influences music being composed on the African continent.
(С) Many novels written in Canada by Chinese immigrants exhibit narrative themes very similar to those found in Chinese folktales.

(B) They fueled his interest in pursuing a career in art history.
(С) They were used in Porter’s book to show the extent of African influence on African-American art.
(D) They were a deliberate attempt to prove his theories about art history.
