  1. Look at the given series:

    What number should come next?
    1. 48
    2. 24
    3. 40
    4. 64

    Answer: B. 24

    Explanation: This is an alternating series. Odd terms are obtained by multiplying every consecutive term by 3. Third term is generated by multiplying 3 with the first term. Fifth term is generated by multiplying 3 with the third term and so on. Even terms are obtained by multiplying every consecutive term by 2. Fourth term is generated by multiplying 2 with the second term. Sixth term is generated by multiplying 3 with the fourth term and so on.

    Answer: D. 35

    Explanation: Second term is generated by subtracting 3 from the first term. Third term is generated by subtracting 2 from the second term. Fourth term is generated by subtracting 3 from third term and so on.


  4. Look at the given series:

    What number should come next?
    1. 1/17
    2. 1/19
    3. 1/21

  6. Look at the given series:

    What number should come next?
    1. 34
    2. 47
    3. 50
    4. 49
    View Answer

    Answer: A. 34

    Explanation: This is an alternating series. Every odd term is obtained by adding 10 to the previous odd term. Every even term is obtained by adding 9 to the previous even term.


  7. Look at the given series:

    What number should come next?
    1. 520
    2. 690
    3. 3125
    4. 420
    View Answer

    Answer: C. 3125

    Explanation: Every term in raised to the power its position in the series: 11 = 1
    22 = 4
    33 = 27
    44 = 256
    55 = 3125


  8. Look at the given series:

    What number should come next?
    1. 67/76
    2. 65/56
    3. 67/70
    4. 65/76
    View Answer

    Answer: B. 65/56

    Explanation: Numerator in each term is formed by adding 2 to the numerator of the previous term. Denominator is obtained by reversing the digits of the numerator.


  9. Look at the given series:

    What number should come next?
    1. 53/8
    2. 55/8
