Q:

# In the following question, various terms of an alphanumerical series are given with one or more terms missing as shown by (?). Choose the missing terms out of the given alternatives. Q1F, S2E, U6D, W21C, ?

 A) Z88B B) Y88B C) Y44B D) K25P

Explanation:

The first letter moves two steps forward. The last letter moves one steps backward. The number series runs as follows :
1 x 1 + 1 = 2
2 x 2 + 2 = 6
6 x 3 + 3 = 21
21 x 4 + 4 = 88.

Q:

The missing number in the series 9 81 ? 6561 59049

 A) 729 B) 3561 C) 4213 D) None of the above

Explanation:

The given series is 9 81 ? 6561 59049

It follows a pattern that

9

81 = 9 x 9

729 = 9 x 9 x 9

6561 = 9 x 9 x 9 x 9

59049 = 9 x 9 x 9 x 9 x 9

Hence, the missing number in the series is 729.

Q:

Find the next number in the given number series?

6, 6, 12, 36, 144, 720, ?

 A) 4320 B) 3547 C) 2154 D) 1765

Explanation:

The given series is 6, 6, 12, 36, 144, 720, ?

6

6 x 1 = 6

6 x 2 = 12

12 x 3 = 36

36 x 4 = 144

144 x 5 = 720

720 x 6 = 4320

Hence, the next number in the given number series is 4320.

Q:

Find the next number in the given number sequence?

4, 15, 37, 81, ?

 A) 196 B) 169 C) 144 D) 121

Explanation:

The given number series follows a pattern that, 4, 15, 37, 81, ?

4

4 + 11 = 15

15 + 22 = 37

37 + 44 = 81

81 + 88 = 169

Hence, the next number in the sequence is 169.

Q:

Find the next number in the series

404, 415, 402, 413, 400, ?

 A) 411 B) 421 C) 417 D) 414

Explanation:

The given series 404, 415, 402, 413, 400, ? follows a pattern that,

404

404 + 11 = 415

415 - 13 = 402

402 + 11 = 413

413 - 13 = 400

400 + 11 = 411

Hence the next number in the given number series is 411.

Q:

Find the next number in the given number sequence?

101, 98, 93, 86, 75, ?

 A) 62 B) 68 C) 71 D) 73

Explanation:

The given number sequence is 101, 98, 93, 86, 75, ?

101

101 - 3 = 98

98 - 5 = 93

93 - 7 = 86

86 - 11 = 75

75 - 13 = 62

Here the series follows a pattern that consecutive subtraction of prime numbers.

Hence, the next number in the sequence is 62.

Q:

Find the next number in the given sequence?

11, 17, 39, 85, ?

 A) 133 B) 143 C) 153 D) 163

Explanation:

Her the given number series is 11, 17, 39, 85, ?

Hence, the next number in the given sequence is 163.

Q:

Next number in the given series is

9 7 10 6 11 ?

 A) 5 B) 4 C) 13 D) 15

Explanation:

The given number series is 9 7 10 6 11 ?

Here in this we have two number sequences, they are

9, 10, 11, ... and 7, 6, 5, ...

Hence, the next number in the given number series is 6 - 1 = 5.

Q:

Find the missing number in the given number series?

1 8 36 ? 1100 7701

 A) 97 B) 129 C) 164 D) 183

Explanation:

The given number series is 1 8 36 ? 1100 7701

It follows a pattern that,

1

1 x 3 + 5 = 8

8 x 4 + 4 = 36

36 x 5 + 3 = 183

183 x 6 + 2 = 1100

1100 x 7 + 1 = 7701

Hence, the missing number in the given series is 183.
