Question

The sum of 3 consecutive integers is 60. What is the value of the third integer?

Answer 1

We can express the first number as x and the next numbers as x+1, and x+2 (since they're consecutive

so

x+x+1+x+2 = 60
3x+3=60
3x=60-3
3x=57
x=19
x+1=20
x+2= 21

The three numbers are 19, 20, and 21
