WebThe sequence of partial sums of a convergent alternating series oscillates around the sum of the series if the sequence of n th terms converges to 0. That is why the Alternating Series Test shows that the alternating series ∑∞k = 1( − 1)kak converges whenever the sequence {an} of n th terms decreases to 0. WebIf the series has alternating signs, the Alternating Series Test is helpful; in particular, in a previous step you have already determined that your terms go to zero. However, the … WebNov 16, 2024 · The first series is nothing more than a finite sum (no matter how large \(N\) is) of finite terms and so will be finite. So, the original series will be convergent/divergent only if the second infinite series on the right is convergent/divergent and the test can be done on the second series as it satisfies the conditions of the test. botanical garden in vancouver bc
