    Let us say that the first number is X

    (between every two odd integers 2 numbers are there eg. 3,5,7,9,11,13, etc.)

    So the 2nd number is X+2

    After adding 2 to the 2nd number you'll get 3rd number to be X+4

    Now we will add the three numbers and show that theirbsum equals to 225

    X + X+2 + X+4 = 225

    X+X+X + 2+4 = 225

    3X + 6 = 225

    3X = 225 - 6

    3X = 219

    X = 219/3

    X = 73

    Therefore,

    The first number i. e, X = 73

    The second number i. e X+2 = 73 + 2 = 75

    The third number i. e X+4 = 73 + 4 = 77
