the three numbers are 73, 75, and 77, their sum is 225, square root of 225 is 15.

i guess i can explain my thought process, although its weak at best. if you let n, be the middle number, then the 3 consecutive odd numbers are:
$$n-2, n, n+2$$
their sum is 3n.
so you want 3n to add up to a perfect square.  that means that n needs to be factorable into 3*(some other square).
so i randomly picked squares and came across 25.  3*25 is 75.  3*3*25 = 225, so on and so forth.
