Abstract

Everyone knows that (3, 4, 5) is a Pythagorean triple (‘PT’); for, the numbers satisfy the Pythagorean relation 3^2 +4^2 =5^2. Indeed, it is a Primitive Pythagorean triple (‘PPT’) since the integers in the triple are coprime. (See the Problem Corner for definitions of unfamiliar terms.) But this triple has a further property: its entries are in arithmetic progression for, 3, 4, 5 forms a three-term AP with common difference 1. Naturally, our curiosity is alerted at this point.
