    So, let's imagine n to be our first odd number, the next one will be a non odd, so the other next will be, so, n + 2, the same to the next term, so, n + 4

    n + (n + 2) + (n + 4) = - 51

    3n + 6 = - 51

    3n = - 51 - 6

    3n = - 57

    n = - 19

    The integers are - 19, - 17, - 15

    -18, - 17, - 16

    Step-by-step explanation:

    Let the number be represented with Z,. i. e.

    Let the number be represented with Z,. i. e Z., Z+1, Z+2

    Let the number be represented with Z,. i. e Z., Z+1, Z+2

    Z + (Z + 1) + (Z + 2) = - 51

    Z + Z + Z + 1 + 2 = - 51

    3Z + 3 = - 51

    3Z = - 51 - 3

    3Z = - 54

    Z = - 54/3

    Z = - 18

    Hence the numbers are - 18, - 17, - 16
