Answers:
1. (b)
2. (c) : The
pattern is - 1, - 2, ...
Missing
number = 17 - 3 = 14.
3. (b) :
Clearly, the given series consists of prime numbers starting from 2. The prime
number after 11 is 13. So, 13 is the missing number.
4. (c): The
pattern is + 5, + 10, + 15, + 20,...
Missing
number = 56 + 25 = 81.
5. (c): The
pattern is + 5. + 7, + 9, + 11,...
Missing
number =33 + 13 = 46.
6. (b) :
Each term of the given series is obtained by multiplying its preceding term by
3.
Missing
number = 81 x 3 = 243.
7. (a)
8. (a): The
pattern is + 3, + 4,...
Missing
number = 9 + 5 = 14.
9. (b): The
pattern is + 4 + 8, + 12, + 16....
Missing
number = 45 + 20 = 65.
10. (c):
Each number in the series is the preceding number multiplied by 2 and then
increased by 1.
Thus. (3 x
2) + 1 = 7, (7 x 2) + 1 = 15, (15 x 2) + l=31 and soon.
Missing
number =(63 x 2) + 1 = 127.
11. (d) :
The pattern is + 5, + 9 , + 21, + 25
Missing
number = 15 + 13 = 28.
12. (c):
Each term in the series is the sum of the preceding two terms. Thus, 1 + 2 = 3;
2 + 3 = 5; 3 + 5 = 8 and so on.
Missing
number = 5 + 8 = 13.
13. (d) :
Each term of the series is obtained by multiplying the preceding term by 3.
Missing
number = 13.5 x 3 = 40.5.
14. (c)
15. a
16. (d): The
sequence is a combination of two series :
I. 19, 38,
114, __
and
II. 2, 3, 4
The pattern
followed in I is x 2, x 3, ...
Missing
number = 114 x 4 =456.
17. (b)
18. (d)
19. (d): The
pattern is x 2, x 3, x 4,...
Missing
number = 72 x 5 = 360.
20. (c):
Each number in the series is the product of the digits of the preceding number.
Thus, 6 x 6
= 36 3 x 6 = 18 and so on.
Missing
number =1 x 8 = 8.
21. (b)
22. (a)
23. (c)
24. (a)
25. (b)
26. (b)
27. (d)
28. (c)
29. (c)
30. (c)
31. (b)
32. (c)
33. (b)
34. (a)
35. (c)
36. (b)
37. (c)
38. (d)
39. (c)
40. (b)
41. (b)
42. (d)
43. (c)
44. (b)
45. (c)
46. 145
47. (a): The
pattern is +20, +40, + 80,...
Missing
number = 152 + 160 = 312.
48. (d): The
sequence is a combination of two series :
I. 3, 5, 7,
9
and
II. 6, 20,
42, __
The pattern
followed in II is + 14, + 22,...
Missing
number = 42 + 30 = 72.
49. (c): The
sum of any three consecutive terms of the series gives the next term.
Thus. 1 + 3
+ 4 = 8; 3 + 4 + 8 = 15; 4 + 8 + 15 = 27 and so on.
Missing
number 8 + 15 + 27 = 50.
50. (d): The
pattern is + 13, + 26, + 39,...
