Can an alternating series ever be absolutely convergent?

WebIn the previous set of notes, we investigated the alternating series. We learned a test that we could use to determine if this type of series converges or diverges. Now the question is how can we determine if both the positive term series and the related alternating series converge or diverge or if only one of them converges.
