    Answer:

    • The odd integers are -11, -9, -7

    Step-by-step Explanation:

    Let the three consecutive odd integers be x, x + 2 and x + 4 because odd integers are in the gap of 2.

    GiveN:

    • The difference of thrice the smallest and twice the largest is -19.

    This can be written as:

    ➛ 3(x) – 2(x + 4) = -19

    ➛ 3x – 2x – 8 = -19

    ➛ x – 8 = -19

    ➛ x = -11

    Then:

    The consecutive odd integers are:

    • x = -11
    • x + 2 = -9
    • x + 4 = -7
