I am working on another problem, very similiar but I can't solve it entirely and I think it's because I am not aware of what I can and can't do.

For instance, you pointed out that

F(n-1)+F(n+2) = F(n-1)+F(n+1)+F(n)

... yet I don't understand how you arrived at that conclusion. I guess what I need is a little crash course on how to manipulate recursive relations (similar to what you learn while handling exponents).

I am realizing that when the terms are similar and of the same type (i.e subtraction or addition, its easy to manipulate them). However, what can i do with something like the equation written above and what rules must be enforced.

P.s sorry if this seems convoluted but my goal is to actually learn how this stuff works, not just hunt down answers to my homework. I am sure you can respect that.
