If you would like to know which are these 3 consecutive integers, you can calculate this using the following steps:
n + (n + 1) + (n + 2) = 48
n + n + 1 + n + 2 = 48
3 * n + 3 = 48
3 * n = 48 - 3
3 * n = 45 /3
n = 45 / 3
n = 15
n + 1 = 16
n + 2 = 17
15 + 16 + 17 = 48
The correct result would be 15, 16 and 17.
