Sorry, you acutally answered my question completly. I had different expectations and didn't want to see that you are right... ;)

comment Linear recursion with coefficients depending on n
You were some seconds faster... :) Since there is a genreal method for all linear recursions, I thought maybe this could be extended to this case somehow. But if you say that you don't think so it's also a very useful answere!

Yeah you are right of course, but there are helpful methods anyway. Either through generating functions or the characteristic polynomial, see here for example.

comment Linear recursion with coefficients depending on n
Well also if have specefic $(b_n)_{n≥0}$ and $(c_n)_{n≥0}$, it might be really difficult to find the solution if I dont' have the right idea. I was wondering if there is something like a characteristic polynomial for this case.

Uh yes, thanks a lot! I totally forgot that I've to deal with labeled structures.
