### Taylor series with Fibonacci coefficients

Let $\{a_n\}$ be the Fibonacci numbers given by $a_0=0,a_1=1,a_{n+2}=a_{n+1}+a_n$ for $n\geq 0$. Prove that $f(z)=a_0+a_1z+a_2z^2+\ldots$ is a rational function, and determine which rational ...

### Proof That the Ratio of Sucessive N-nacci Numbers Tends to 2.

For the paper that I'm working on involving N-nacci Recursion Formulas I need to prove that $$\lim_ {n \to \infty}\lim_{a \to \infty} \left | \frac{f^{(n)}_{a+1}}{f^{(n)}_a} \right | = 2$$ To start ...

### N-nacci Identities: The Final Question (Generalizing Time!)

Okay so here is my personal work on the problem set. I only have question 5 remaining which involves generalization of any recursive sequence. $n$'s correspond to the $n$ in n-nacci. I hope to write ...
