I am trying to practice for an exam but can't do this question:(adsbygoogle = window.adsbygoogle || []).push({});

does the series [tex]\((-1)^n/ln(n)[/tex] from n = 2 to infinity converge abs/conditionally/diverge?

I know if a do an alternating series test, the integral will converge because lim goes to 0 and a(n+1)<an.

But how can I prove that it's conditionally convergent? I did the limit test but it says that it is absolutely convergent, which is not the answer(it is supposed to be conditionally).

Thank you...
