I have the series

$\frac{1}{2!} + \frac{2}{3!} + \frac{3}{4!} + \text{... }+ \frac{n}{(n+1)!}$

How can I create a compact expression for the sum of the series? Essentially, what is a compact expression for the following?


I'm lost as to where to start.

    $\begingroup$ Did you miss $\frac{2}{3!}$ or was it not part of the series? If it wasn't part of the series, then your summation representation is incorrect. $\endgroup$ – TenaliRaman Aug 26 '16 at 4:57
  • $\begingroup$ Yes I did miss that too. Will fix $\endgroup$ – intboolstring Aug 26 '16 at 4:58
