Your notation for the general term is confusing if not ambiguous: it has the form a/b/c/d. Do you really intend the form to be (a/b)/(c/d)? If so, then why don't you take a look at what happens to the nth term as n tends to infinity, and then apply an appropriate theorem? mizhael wrote: > sum((-6*2^n*n+3*2^n+2*3^n*n)/(3^n)/(n^2-3*n+2)/(2^n),n = 1 ..
