Let
1st Integer = x
2nd Integer = x+1
3rd Integer = x+2
=================================================
Given
x+x+1+x+2=18
3x+3=18
3x=18-3
3x=15
x=15/3
x=5
==================================================
1st Integer = x =5
2nd Integer = x+1 = 5+1=6
3rd Integer = x+2=5+2=7
====================================
Check
5+6+7=18
11+7=18
18=18
