Let x = 1st odd integer
x + 2 = 2nd odd integer
x + 4 = 3rd odd integer
------------------------------
(x) + (x + 4) = (x + 2) + 15
x + x + 4 = x + 2 + 15
----------------------------
Combine like terms.
2x - x = 17 - 4
x = 13
x + 2 = 13 + 2 = 15
x + 4 = 13 + 4 = 17
--------------------------
The three consecutive odd integers are 13, 15, and 17.
