Yes, exactly (for instance the Lucas sequence ...,1,3,4,7,11,18,...). Jim On Wednesday, August 9, 2017, Andy Latto <andy.latto@gmail.com> wrote:
I assume it means f(n) + f(n + 1) = f(n + 2) for all n in Z.

Would you be so kind as to define what a "two-sided generalized Fibonacci sequence means"? Sorry, I'm too dumb to be able to figure out what the general term is from "n-m,m,n,m+n".

----- Given a two-sided generalized Fibonacci sequence ...,n-m,m,n,m+n,... (with m,n in Z and not both zero), must there exist a two-sided arithmetic progression ...,a-d,a,a+d,... (with a,d in Z and d nonzero) that is disjoint from it? -----
