Helllo, frnds,

Please help me in solving this series.

S(n) = (1/2) + (2^2)/2^2 + (3^2)/2^3 + (4^2)/2^4 + .........

So, we can write this series as

Sum of T(n) = [(n^2)/(2^n)] ...

Any ideas ..please help..

Thanx..

The placement of this question in an elementary mathematics forum is puzzling.

This requires a bit of calculus at a higher level to solve.

Questions: Do you simply want a answer for some simple reason?

Or are you required to supply reasons for the particular answer?

Please respond so that we know how to answer and to what extent the answer should be.
