    advanced calculus

    how do you investigate the convergence of the series?

    a) 1/2 - 1/20 + 3/38 + 4/56 + 4/74

    b) 1/4 + 9/64 + 225/2304 + 11025/147456

    You can actually work out the sum...

    However, if you want to give us a general term for an infinite sum, we'd be happy to help.
