Algebra of Limits for Series

In summary, the series from n=1 to ∞ of (1/2+(-1)n)/n does not converge, and splitting it into two separate series does not help in proving convergence. The first series is convergent, while the second is not.

1. Does the series from n=1 to ∞ of (1/2+(-1)n)/n converge?



2. Am I able to split up the series into Ʃ1/2n + Ʃ(-1)n/n even though they are not convergent? I'm not sure how else to prove for convergence. I have tried all the tests...

One of those is convergent. The other is not. So, splitting them up does help.
