It is really not obvious to me which values of p make ∑∞21nplog(n) converge only using comparison test (general comparison test, limit comparison test).
Am I missing something ? I knew that the series converges for p>1 and diverges for p≤0 by comparing it with 1/np but that's it.
Edit. I know it can be solved using integral test, cauchy condensation test, etc. but I am just wondering if there is a comparison to some other series that directly results in divergence of this one for p≤1 (or just p<1 is fine, too.)
Answer
For p<1 compare with ∑1/nq with $p0lim$
