if the first number is x
then the 2nd number is x + 2 two more than 1st
then the 3rd number is x + 2 + 2 two more than the 2nd
now just add them up = 60
x + x + 2 + x + 2 + 2 = 60 solve for x
(x) + (x+2) + (x+4) = 60
3x + 6 = 60
3x = 54
therefore the second number is 20 because 18+2=20
and the third is 22 because 20+2=22 :)

Thanks so much.
let first number is x
then second number is x+2
so the third number is x+2+2
as per question
(x)+(x+2)+(x+2+2) = 60
3x+6 = 60
x= 54/3 =18
so 1st number is 18
second number is 20 and third number is 22
