It need not be. 2 and 3 are consecutive integers and their sum is 5, not 31.
The integers are -4, -3, -2, -1, 0, 1, 2, 3, 4 and 5. The largest is five.
Divide the sum of the three consecutive odd integers by 3: -3 /3 = -1. The smallest of these integers will be two less than -1 and the largest will be two more than -1, so the three consecutive odd integers will be -3, -1, and +1.
