Question

    What number should come next in the series: 100, 101,

    99, 100, 98, 99, 97, ___?
    A 98 Correct Answer Incorrect Answer
    B 97 Correct Answer Incorrect Answer
    C 96 Correct Answer Incorrect Answer
    D 95 Correct Answer Incorrect Answer

    Solution

    This is a combination of an addition and subtraction series, in which every even term is arrived at by adding 1 to the previous term and every odd term is arrived at by subtracting 2 from the previous term. The next term in the series will be an even term, So it should be 97 + 1 = 98.   Hence, the correct answer is (A).
