For the following series sum(an) between n=2, n=infinity determine if the series converges and if so find the limit? Such that
an=1/(n(n^2-1))
I've expressed (an) in partial fractions so that
an=-1/n + 1/(2(n+1)) + 1/(2(n-1))
but can't seem to get any further than this?
Where should I go from here??
