On Sums of Cubes of Fibonacci Numbers

  • Chapter
Applications of Fibonacci Numbers

Abstract

Our story begins with one of the simplest, prettiest, and easiest to prove of all the Fibonacci summation formulas, the formula

$$ \sum\limits_{{k = 1}}^n {F_k^2 = {F_n}{F_{{n + 1}}}} $$
(1)

for the sum of the squares of the consecutive Fibonacci numbers. We were struck by the elegance of this formula—especially by its expressing the sum in factored form—and wondered whether anything similar could be done for sums of cubes of Fibonacci numbers. This paper is a report of some of our discoveries.
