Summary

Summary: The Fibonacci sequence's initial terms are $F_{0}=0$ and $F_{1}=1$, with $F_{n}=F_{n-1}+F_{n-2}$ for $n \geq 2$. We define the polynomial sequence ${\bf p}$ by setting $p_{0}(x)=1$ and $p_{n}(x)=xp_{n-1}(x)+F_{n+1}$ for $n \geq 1$, with $p_{n}(x)=\sum_{k=0}^{n}F_{k+1}x^{n-k}$. We call $p_{n}(x)$ the Fibonacci-coefficient polynomial (FCP) of order $n$. The FCP sequence is distinct from the well-known Fibonacci polynomial sequence.
