The sum of three consecutive integers is 69.
(69 X (69+1)) / 2=2,415
Or you can group them into pairs:1+ 69, 2+68, 3+67........etc.=70 X (69/2)=2,415
SORRY, I MISREAD THE QUESTION!!!!!!!!!
If first number is n, n+1, n+2, we have: n + n+1 +n+2=69
3n=69-3=66
n=66/3=22
So the THREE numbers: 22 + 23 +24=69
