Abstract
A well-known identity is
where F k and L k are the Fibonacci and Lucas numbers, respectively. With the definitions \(F_{-k} = (-1)^{k + 1}F_k\) and \(L_{-k} = (-1)^kL_k\) formula (1.1) is true for all integer m and n. The identity is easy to prove, and it is evidently useful; Rokach [11], for example, proved that (1.1) is about 2.88 times more efficient than the usual Fibonacci recurrence for computing the Fibonacci numbers.
