    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=60-6 3x = 54 x=54/3 x=18 therefore the second number is 20 because 18+2=20 and the third is 22 because 20+2=22 :)

    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 3x =60-6 x= 54/3 =18 so 1st number is 18 second number is 20 and third number is 22 You can practice different number properties :http://www.mathcaptain.com/number-sense/properties-of-numbers.html problems for your improvement.
