An is a sequence and Snis a sequence of partial sums of the series nΣ1 to infinity of An

If An is greater than 0 for all N and mΣ1 to infinity of A2m diverges, does An diverge??

I have no idea what the M and 2m have to do with anything, I'm guessing its just another variable as N has lready been used but I've never seen 2M before (I ave seen N+1)
