ZS-Associates Reasoning Question

DIRECTIONS for questions 1 to 4: What will come in place of question mark (?) in the given number series?
  1. 15 27 37 45 51 ?
    1. 158
    2. 80
    3. 65
    4. 74
    5. 55

    Answer: Option E.
    Given series is: 15 27 37 45 51 ?
    And the pattern is 27 – 15 = 12, 37 – 27 = 10, 45 – 37 = 8, 51 – 45 = 6.
  2. 700 457 376 349 340 ?
    1. 266
    2. 329
    3. 304
    4. 337
    5. 307

    Answer: Option D.
    Given series is:
    700 457 376 349 340 ?
    Pattern is 700 – 457 = 243, 457 – 376 = 81, 376 – 349 = 27, 349 – 340 = 9
    Thus, the next term is 340 – 3 = 337
  3. 1 2 6 21 88 ?
    1. 425
    2. 475
    3. 295
    4. 445
    5. 395

    Answer: Option D.
    Given series is:
    1 2 6 21 88 ?
    Pattern is 1×1+1= 2
    2×2+2= 6
    6×3+3=21
    21×4+4= 88
    88×5+5= 445
    So the next term of the series is = 445
  4. 19 20 16 25 9 ?
    1. 45
    2. 55
    3. 59
    4. 34
    5. 81

    Answer: Option D.
    Given series is:
    19 20 16 25 9 ?
    Pattern is 19 – 20 = -1
    20 – 16 = 4
    16 – 25 = -9
    25 – 9 = 16
    So, next term of the series is = 9 – (-25) = 34
