    Answer: 16, 17 and 18

    Step-by-step explanation:

    Let the consecutive natural numbers be x, x+1, and x+2. We are informed that the sum of the first and the second is 15 more than the third. This will be:

    [x + x + 1] = [x + 2] + 15

    2x + 1 = x + 2 + 15

    2x + 1 = x + 17

    2x – x = 17 – 1

    x = 16

    The numbers are 16, 17 and 18.
