    Answer:

    D) 32

    Step-by-step explanation:

    Given;

    series: 56, 54, 50, 38, 34, ….

    find the difference between successive numbers;

    56         54        50             38            34             x

         2            4             12              4             2            

    The highest difference between the numbers is  12, after which it decreases to 4 and finally back 2.

    The next number “x” is calculated as;

    34 – 2  = x

    34 – 2 = x

    32 = x

    Therefore, the next number should be 32.
