Math Problem Statement

The sums of the squares of consecutive Fibonacci numbers beginning with the first Fibonacci number form a pattern when written as a product of two numbers.

Solution

Yes, there is indeed an interesting pattern that emerges from the sums of the squares of consecutive Fibonacci numbers. Specifically, the sum of the squares of the first nn Fibonacci numbers follows this identity:

F12+F22+F32++Fn2=FnFn+1F_1^2 + F_2^2 + F_3^2 + \cdots + F_n^2 = F_n \cdot F_{n+1}

Where FnF_n is the nn-th Fibonacci number.

Example:

  1. For n=1n = 1: F12=12=1F_1^2 = 1^2 = 1 We see that: 1=F1F2=111 = F_1 \cdot F_2 = 1 \cdot 1

  2. For n=2n = 2: F12+F22=12+12=1+1=2F_1^2 + F_2^2 = 1^2 + 1^2 = 1 + 1 = 2 This matches: 2=F2F3=122 = F_2 \cdot F_3 = 1 \cdot 2

  3. For n=3n = 3: F12+F22+F32=12+12+22=1+1+4=6F_1^2 + F_2^2 + F_3^2 = 1^2 + 1^2 + 2^2 = 1 + 1 + 4 = 6 And indeed: 6=F3F4=236 = F_3 \cdot F_4 = 2 \cdot 3

This pattern holds for all Fibonacci numbers and is a beautiful property of these numbers. It allows us to compute sums of Fibonacci squares quickly by using products of two consecutive Fibonacci numbers.
