  2. let's consider three number p, q, r

    by condition, q - p = r - q → q = (p + r) / 2.
    It means that the 2nd number is in between 1st and 3rd number.

    So the number would be 1 * (3/2) * 2 = 3

  5. It is -3, -1, and 1

    -3 x -1 x 1 = 3
    -1 - (-3) = -1 + 3 = 2
    1 - (-1) = 1 + 1 = 2
