Hi all I google about but still nothing my question is this. Considering a linear recurrent sequence where the n+i term is the linear sum of the previous k terms is there something like a Binet Formulas to express the n+1 term as power of the previous k terms?
Thank is someone could help


$$\sum_{i=1}^k P_i(n)\alpha_i^n$$, where the $P_i(n)$ are polynomials in $n$. – Joe Silverman Aug 19 2011 at 11:52
