# Math Help - linear recurrence equation with non constant coefficients

1. ## linear recurrence equation with non constant coefficients

I would solve the following recurrence equation:

$a_{n+1} = a_n + 1/(2(c+n-1))*a_{n-1}$

where c>0 is a fixed constant.

It is linear (and that's good), but there's a non constant coefficient.. There's a way to find an explicit solution?
