calculus - Does this series converge conditionally suminftyn=1frac(1)nnfrac110


n=1(1)nn110




According to my understanding, if |an| diverges but an converges, then the series is conditionally convergent.




For |an| my series can be test via the p-series test and since 110<1 it diverges.



So next I test an using the alternating series test and find that it is a decreasing series and the limit converges to 0.



Thus, I came to the conclusion that this is conditionally convergent. Is this correct?
