深入理解无穷级数和的定义(the sum of the series) Given an infinite sequence (a1, a2, a3, ...), a series is informally the form of adding all those terms together: a1 + a2 + a3 + ···. To emphasize that there are an infinite number of terms, a series is often called an infinit...

, thus defining the sum of a series as the limit of the sequence of its partial sums is intuitively plausible. Given the definition gives the true sum of the infinite series, the statement that 0.999… = 1 can itself be interpreted and proven as: 0.999…=limn→∞0.99…9 n=limn→∞∑...

Writing the right-hand side as , the equation becomes , 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, . Find the sum of the terms in the sequence 1, 2, 3, ...

A series is the sum of the terms in a sequence, so an arithmetic series is the sum of the terms in an arithmetic sequence. Let S represent the sum: S=a_1+a_2+a_3++a_(n-2)+a_(n-1)+a_n. Write the sum again, except write the terms from last term to first term: S=a...
