39
11, 12, and 13
36
The answer is 12 because I took 36 divided by 3 and got 12
It need not be. 2 and 3 are consecutive integers and their sum is 5, not 31.
4, 5 & 6 (16 + 25 + 36)
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.
They are are 62, 63 and 64.

3 consecutive even integers whose sum is 396 are 130, 132 and 134.
The sum of even integers cannot end with 9. why not
4 and 5
