2. Let $F_i$ be the Fibonacci sequence. Prove by induction that (a) $\sum_{i=1}^{n} F_i = F_{n+2}$ (b) $\sum_{i=1}^{n} F_i^2 = F_n F_{n+1}$ (c) $F_n^2 - F_{n-1} F_{n+1} = (-1)^{n-1}$

          2. Let $F_i$ be the Fibonacci sequence. Prove by induction that
(a) $\sum_{i=1}^{n} F_i = F_{n+2}$
(b) $\sum_{i=1}^{n} F_i^2 = F_n F_{n+1}$
(c) $F_n^2 - F_{n-1} F_{n+1} = (-1)^{n-1}$

2. Let Fi be the Fibonacci sequence. Prove by induction that
(a) ∑i=1^n Fi = Fn+2
(b) ∑i=1^n Fi^2 = Fn Fn+1
(c) Fn^2 - Fn-1 Fn+1 = (-1)^n-1
