You can put this solution on YOUR website!
n is the first number.
n + 1 is the second number.
n + 2 is the third number.

n + (n + 1) = (n + 2)

solve for n.

subtract n from both sides of the equation and subtract 1 from both sides of the equation to get:

n = 1

that's your answer.

n = 1
n+1 = 2
n+3 = 3

1 + 2 = 3

answer is confirmed as good.
