let first integer be x, second one is x%2B1, and third one is x%2B2
x%2B%28x%2B1%29%2B%28x%2B2%29=15
x%2Bx%2B1%2Bx%2B2=15
3x%2B3=15
3x=15-3
3x=12
highlight%28x=4%29->first integer
second one is x%2B1=4%2B1=highlight%285%29
and third one is x%2B2=4%2B2=highlight%286%29

check their sum:
x%2B%28x%2B1%29%2B%28x%2B2%29=15
4%2B5%2B6=15
15=15
