What are three consecutive odd integers that have a sum of 39?

Consecutive odd integers ascend by 2 units so the integers can be represented with x, x + 2, and x + 4. The word sum implies an addition.

x + x + 2 + x + 4 = 39
3x + 6 = 39
3x = 33
x = 11

The three consecutive odd integers are 11, 13, and 15
