  • 2. 

    Look at this series: 31, 29, 24, 22, 17, ... What number should come next?

    • 10

    • 11

    • 12

    • 15

    Correct Answer
    A. 15
    Explanation
    The series is decreasing by 2, then decreasing by 5, then decreasing by 2 again. This pattern suggests that the next number should decrease by 5, resulting in the number 15.

    Rate this question:

  • 3. 

    Look at this series: 53, 53, 40, 40, 27, 27, ... What number should come next?

    • 24

    • 14

    • 25

    • 13

    Correct Answer
    A. 14
    Explanation
    The series alternates between two sets of numbers: 53 and 40, and 40 and 27. In each set, the numbers decrease by 13. Therefore, the next set of numbers should be 27 and 14. The number that follows 27 is 14.

    Rate this question:

  • 4. 

    Look at this series: 201, 202, 204, 207, ... What number should come next?

    • 209

    • 208

    • 211

    • 200

    Correct Answer
    A. 211
    Explanation
    The series follows a pattern of adding 1, then 2, then 3, and so on. Starting with 201, we add 1 to get 202, then add 2 to get 204, then add 3 to get 207. The next number in the series should be obtained by adding 4 to the previous number, which gives us 211.

    Rate this question:

  • 5. 

    Look at this series: 2, 1, (1/2), (1/4), ... What number should come next ? 

    • (1/3)

    • (1/8)

    • (2/16)

    • (2/8)

    Correct Answer
    A. (1/8)
    Explanation
    The pattern in the series is that each number is half of the previous number. Starting with 2, we divide by 2 to get 1, then divide by 2 again to get 1/2, and so on. Therefore, the next number in the series should be half of the previous number, which is (1/4) divided by 2, resulting in (1/8).

    Rate this question:

  • 6. 

    Look at this series: 80, 10, 70, 15, 60, ... What number should come next?

    • 50

    • 25

    • 30

    • 20

    Correct Answer
    A. 20
    Explanation
    The pattern in the series is that the first number is subtracted by 10, and the second number is added by 5. This pattern alternates for each pair of numbers. So, starting with 80, we subtract 10 to get 70, then add 5 to get 75. Continuing this pattern, we subtract 10 from 75 to get 65, then add 5 to get 70. Therefore, the next number in the series should be 20, as we subtract 10 from 70.

    Rate this question:

  • 7. 

    Look at this series: 5.2, 4.8, 4.4, 4, ... What number should come next?

    • 3.6

    • 3.4

    • 4.4

    • 3

    Correct Answer
    A. 3.6
    Explanation
    The pattern in the series is that each number is decreasing by 0.4. Starting from 5.2, each subsequent number is 0.4 less than the previous number. Therefore, the next number in the series should be 3.6, as it is 0.4 less than 4.

    Rate this question:

  • 8. 

    Look at this series: 1.5, 2.3, 3.1, 3.9, ... What number should come next?

    • 4.7

    • 4.6

    • 5.7

    • 6.7

    Correct Answer
    A. 4.7
    Explanation
    The series follows a pattern where each number is obtained by adding 0.8 to the previous number. Starting with 1.5, we add 0.8 to get 2.3, then 0.8 again to get 3.1, and so on. Therefore, the next number in the series should be obtained by adding 0.8 to the previous number, which gives us 3.9 + 0.8 = 4.7.

    Rate this question:

  • 9. 

    Look at this series: 1000, 200, 40, ... What number should come next?

    • 4

    • 8

    • 20

    • 40

    Correct Answer
    A. 8
    Explanation
    The pattern in the series is that each number is divided by 5 to get the next number. Starting with 1000, when we divide it by 5, we get 200. Then, when we divide 200 by 5, we get 40. Therefore, the next number in the series should be 40 divided by 5, which is 8.

    Rate this question:

  • 10. 

    Look at this series: 14, 28, 20, 40, 32, 64, ... What number should come next?

    • 56

    • 128

    • 64

    • 58

    Correct Answer
    A. 56
    Explanation
    The series alternates between doubling the previous number and subtracting 8. Starting with 14, the next number is obtained by doubling 14 to get 28. Then, subtracting 8 from 28 gives 20. Continuing this pattern, the next number is obtained by doubling 20 to get 40, and then subtracting 8 to get 32. Therefore, the next number in the series should be 64.
