Answer:
47, 48, 49
Explanation:
Consecutive numbers have a difference of 1 between them.
let n be the first number then n + 1 and n + 2 are the next 2 numbers, thus
n + n + 1 + n + 2 = 144 ← sum of 3 consecutive numbers, that is
3n + 3 = 144 ( subtract 3 from both sides )
3n = 141 ( divide both sides by 3 )
n = 47
Thus the 3 numbers are 47, 48 and 49
