Question 277042
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.
