Recursion relation

Hi mathgroup, I'm trying to implement the following recursion relation for a certain index function c[i]: c[i] = r[i] - a[i,i-1]*c[i-1] where r[i] and a[i,i-1] are given functions. Namely, I'd like to have a function c[i+n_Integer] giving me the expression of c[i+n] in terms of r[i+n],r[i+n-1],...,r[i] and c[i-1]. DOES ANYBODY KNOW A WAY TO DO THIS ??? Thanks in advance.
