Determine whether each of the following is Always True,
Sometimes True, or Always False. If the statement is Always True or
Always False, provide a brief justification. If the statement is
Sometimes True, provide an example of a series that makes it true
and an example of a series that makes it false. In the following,
{a_n}∞n=1 is a sequence and {s_n}∞n=1 refers to the corresponding
sequence of partial sums.
(a) If lim n→∞ s_n = 0, then lim n→∞...

(1 point) Series: A Series (Or Infinite Series) is obtained from a sequence by adding the terms of the sequence. Another sequence associated with the series is the sequence of partial sums. A series converges if its sequence of partial sums converges. The sum of the series is the limit of the sequence of partial sums For example, consider the geometric series defined by the sequence Then the n-th partial sum Sn is given by tl...
