An Infinite Sequence of Identities Equating the Sum of Squares of Lucas Numbers with the Sum of Squares of Fibonacci Numbers
Description: This research presents a newly discovered relationship between two famous mathematical sequences: the Lucas numbers and the Fibonacci numbers. The author identifies and proves a specific infinite sequence of identities where the sum of squares of any two consecutive Lucas numbers is exactly equal to the sum of squares of two specific Fibonacci numbers. Specifically, it is shown that the sum of the square of the n-th Lucas number and the square of the (n+1)-th Lucas number is identical to the sum of the square of the (n+3)-th Fibonacci number and the square of the (n-2)-th Fibonacci number. The article includes: A detailed introduction to the relationship between these quadratic forms. A comprehensive numerical verification table covering the first twenty instances of the identity, demonstrating its absolute accuracy. A formal mathematical proof using Binet's formula to establish the validity of the identity for all integers n. This work offers a fresh, symmetric perspective on the deep structural connections within integer sequences related to the Golden Ratio.
