Recurrent Relations for Multiple of Triangular Numbers being Triangular Numbers

Number Theory 2021-01-05 v1

Abstract

We search for triangular numbers that are multiples of other triangular numbers. It is found that for any positive non-square integer multiplier, there is an infinity of multiples of triangular numbers that are triangular numbers and recurrent relations are deduced theoretically. If the multiplier is a squared integer, there is either one or no solution, depending on the multiplier value.
