  1. An = 3 n (2- n^2) / [ 2 n^2 (n+2) ]
    An = (3/2) (1/n) (-1) (n^2-2) /(n+2)
    as n gets big, 2 looks small
    An = (-3/2) (1/n) (n^2/n)
    An = -3/2 (n^2/n^2)
    An = -3/2

    Use the ratio test to find whether the series diverges or converges. 1/5^n (1 to infinity) I think the limit converges to 1/5, so the series converges.
