Abstract

We consider for integers k ≥ 2 the k–generalized Fibonacci sequences F(k) := (Fn(k))n2k, whose first k terms are 0, …, 0, 1 and each term afterwards is the sum of the preceding k terms. In this paper, we show that there does not exist a quadruple of positive integers a1 < a2 < a3 < a4 such that aiaj + 1 (ij) are all members of F(k).
