first number = n

the second number is twice as much as the first number
second number = 2n

the third number is two more than the first number
third number = n+2

there are 3 numbers that add up to 90

n + 2n + n+2 = 90
      4n + 2 = 90
          4n = 88
           n = 22

first number = n = 22
second number = 2n = 2(22) = 44
third number = n+2 = 22+2 = 24
