    C 88.75 Correct Answer Incorrect Answer
    D 2592 Correct Answer Incorrect Answer
    E 1300 Correct Answer Incorrect Answer

    Solution

    The series is (x/2) + 4 (repeated) (2592/2) + 4 = 1300, (1300/2) + 4 = 654, (654/2) + 4 = 331, (331/2) + 4 = 169.50, (169.5/2) + 4 = 88.75,..... Therefore it should be 654 in place of 656.
