The document presents 10 problems with numerical sequences and their solutions. Each problem provides a series of numbers and the rule for generating the sequence. The solution identifies which number in the series does not fit the pattern. For example, problem 1 states the series is multiples of 11 except 279. Problem 2 says the terms are alternatively multiplied by 1.5 and divided by 3 except 18.5. And so on for each of the 10 problems.

1. Odd Man Out And Series

2. 1. 22, 33, 66, 99, 121, 279, 594
Solution :
Each Number except 279 is a multiple of 11
A. 22 C. 279
B. 33 D. 594

3. 2. 36, 54, 18, 27, 9, 18.5, 4.5
Solution:
The terms are alternatively multiplied by 1.5
and devided by 3. However 18.5 does not
satisfy it
A. 18 C. 27
B. 18.5 D. 54

4. 3. 582, 605, 588, 611, 634, 617, 600
Solution :
Alternatively 23 is added and 17 is subtracted
from the terms. So, 634 is wrong.
A. 634 C. 588
B. 617 D. 611

5. 4. 3, 10, 21, 36, 55, 70, 105
Solution:
The pattern is 1x3, 2x5, 3x7, 4x9, 5x11, 6x13,
7x15 etc
A. 21 C. 55
B. 36 D. 70

6. 5. 8, 27, 125, 343, 1331
Solution:
The numbers are cubes of primes i.e cubes of
(2, 3, 5, 7, 11 ). so none is wrong
A. 27 C. None Of Above
B. 125 D. 343

7. 6. 125, 123, 120, 115, 108, 100, 84
Solution:
Prime numbers 2, 3, 5, 7, 11, 13 have successively been
subtracted. So, 100 is wrong (108-11=97)
A. 125 C. 108
B. 115 D. 100

8. 7. 8, 13, 21, 32, 47, 63, 83
Solution :
Go on adding 5, 8, 11, 14, 17, 20. So number 47 is
wrong
A. 13 C. 47
B. 21 D. 63

9. 8. 5, 16, 6, 16, 7, 16, 9
Solution :
Terms at odd places are 5, 6, 7, 8 etc and each
term at even place is 16. so, 9 is wrong
A. 16 C. 9
B. 6 D. 7

10. 9. 1, 8, 27, 64, 124, 216, 343
Solution :
The nubers are cubes of (1,2,3,4 etc)
A. 124 C. 27
B. 216 D. 64

11. 10. 46080, 3840, 384, 48, 24, 2, 1
Solution:
The terms are successively divided by 12, 10,
8, 6,....etc. So, 24 is wrong
A. 3804 C. 2
B. 384 D. 24
