3 consecutive odd integers ... x, x + 2, and x + 4

(x + 4) ^2 = (x^2 + (x + 2) ^2) + 15

x^2 + 8x + 16 = x^2 + x^2 + 4x + 4 + 15

x^2 + 8x + 16 = 2x^2 + 4x + 19

2x^2 + 4x + 19 - x^2 - 8x - 16 = 0

x^2 - 4x + 3 = 0

(x - 3) (x - 1) = 0

x - 3 = 0 ... x + 2 = 3 + 2 = 5 ... x + 4 = 3 + 4 = 7

x = 3

so another one that satisfies this is : 3,5,7 <===

x - 1 = 0 x + 2 = 1 + 2 = 3 ... x + 4 = 1 + 4 = 5

x = 1

and another one is : 1,3,5 <===
