The purpose of this research is to describe students' critical thinking ability in solving arithmetic sequence and series questions at Public Senior High School 5 of Jember. The subjects of this research were 29 students of X MIPA 4. They were categorized into 3 groups, comprisingof high, ...
A series is a set of numbers to work with, which may vary as the problem changes.A sequence is a set of numbers which must be in the same order and they do not vary.The sequence may not be in a "logical" order such as 123. They may be 132 or 213, but they always...
interpret“说明”、“阐明”，指用语言或其他方式解释较为难以理解的事物。也可指把一种语言口译出另一种语言。explain“解释”、“说明”，普通用词，用途广泛，指试图说明事物的含义、原因、形成、过程等，以使他人了解和理解。Eg：He makes athletes explain why they made a mistake.他让运动员们...
揭示了级数收敛的必要条件——一般项趋于零。然而，这并非充分条件，我们通过特定数列的例子，说明了收敛条件的复杂性。最后，我们总结了级数研究的若干要点，包括几何级数的收敛特性、harmonic series的发散性，以及级数收敛的充分必要条件。我们特别强调了注意以下四点，以确保深入理解级数与无穷序列的本质。

Writing the right-hand side as n(a_1+a_n), the equation becomes 2S=n(a_1+a_n), so the sum of the first n terms of the arithmetic series, S, is equal to one-half the number of terms multiplied by the sum of the first and last terms. That is, S= n2(a_1+a_n). Find ...
