17, 18 and 19 are the only three consecutive numbers whose sum is 54.

Explanation:

Assuming the first of the 3 consecutive numbers to be n, we then know that (n) + (n+1) + (n+2) = 54.

i.e. (3xxn)+3=54.

Change 3 to the other side 3xxn = 54-3=51,

and that gives you n = 51/3=17.

Therefore n, n+1 and n+2 become 17, 18 and 19 (sum = 54).
