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.
