Question

Three consecutive integers have a sum of 243

Answer 1

Three consecutive integers are n, n+1, and n+2 so

n+n+1+n+2=243

3n+3=243

3n=240

n=80

So the integers are 80,81, and 82

Answer 2

First integer: x
second integer: x+1
third integer: x+2
Set up an equation: 3x+3=243
3x=240
x=80
The integers are 80,81,82
