Answer of Number Series Questions

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.

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,...
Missing number = 80 + 52 = 132.
