I have trouble with alternating series.
I have to test the series for convergence or divergence.
Any help would be appreciated
Thanks!
Hello,
Remember that for an alternating series to converge , you have to check that :

 is a decreasing sequence
But here, one can see that when n approaches high values, +2 can be neglected.
Thus the general term is equivalent to , which is an alternating Riemann series that converges.
