Abstract

Let T > 1 denote a positive integer. Let Un denote the linear recurrence sequence defined by U0 = 0, U1 = 1, and Uk+1 = 2TUk - Uk-1 for k 1. In recent years there have been some improvements on the determination of solutions to the Diophantine equation Un = cx2, where c is a given positive integer. In this paper we use a result of Bennett and the author to determine precisely the integer solutions to the related equation Un = cx2 1, where c is a given even positive integer.
