However, if the set to which the terms and their finite sums belong has a notion of limit, it is sometimes possible to assign a value to a series, called the sum of the series.This value is the limit as n tends to infinity (if the limit exists) of …

NettetLimit Comparison Test. We have seen that the Direct Comparison Test can be inconclusive if the comparison goes in the wrong direction. In these cases, the Limit Comparison Test (LCT) can be used instead. As its name suggests, the LCT involves computing a limit. More precisely, it involves computing the limit of the ratio of a given … Nettet3. okt. 2015 · If lim a n / b n = ∞ and ∑ a n diverges, then ∑ b n diverges.
