You can quickly figure this out by trial and error.Or, you can call the first number "n", the second "n+1", and the third "n+2", and solve the equation:
n + (n + 1) + (n + 2) = -3
0, -1, -2
The numbers are 116, 118 and 120.
There are no three consecutive odd integers who's sum equals 13.
There are no such integers.
The integers are 37, 38 and 39.
That isn't possible. The three consecutive number are assumed to be integers; the sum of three consecutive integers is always a multiple of 3 (try it out).
The integers are 180, 182 and 184.
The numbers are -22, -21 and -20.
25, 27, 29
The average of three numbers which sum to 66 is 66/3 = 22. If 22 is the sum of three consecutive integers, then those three integers are 21,22,23. Kermit Rose
The numbers are 65, 66, and 67..
The numbers are -18, -16 and -14.
There is no set of three consecutive integers for 187.
