1. The problem statement, all variables and given/known data Find if the series is absolutely convergent, conditionally convergent, or divergent. The sum from two to infinity of (-1)^n/lnx. 2. Relevant equations 3. The attempt at a solution I don't know how to integrate 1/lnx, so that failed. The ratio and root test don't seem to simplify matters any further. I wasn't sure of anyway I could use the comparison test or limit ratio test. I used Alternate Series Test so I at least know that it's convergent, but I don't know if it's conditionally convergent or absolutely convergent.
