Let the integers be x + (x+1) + (x + 2)
x + (x+1) + (x + 2) = 267
3x + 3 = 267
3x = 264
x = 88
88+89+90=267
Largest integer=90
Another method
267/3 = 89
It's the average,so it has to be the middle one.
Thus 89, then I took 89 - 1 = 88 and 89 + 1 = 90 and just put them in order.
88+89+90=267
Largest integer=90
