+1

sum of 3 consecutive integers, 

so the first integer is x

second integer is x+1 (Because it is consecutive) then the third is x+2

The sum of them is equal to 15

so

x+x+1+x+2=15

combine like terms

3x+3=15

subtract 3

3x=12

divide by 3

x=4

 

Find each integer just by subsituiting x=4 

first integer is x so it is = 4

second integer is x+1 so it is 5

third integer is x+2 so it is 6

Their product, 4*5*6=120
