Thanks Carl and Daniel, for pointing out the
SeriesTerm function from the RSolve package. 

However, my input got screwed up in copy paste. The
function that I had intended was the generating
function for Legendre polynomials. 

G[u_,x_]=(1 - 2*x*u + u^2)^(-1/2)

And the nth term of which, indeed gives me the
Legendre Polynomials in terms of Gamma function. I am
impressed.

How can I decompose this result into two seperate ones
for even and odd values of n. So as to see the things
in a more familiar form using factorials.

Ash
