Q:

Find the next number in the given number series?

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

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

Answer & Explanation Answer: A) 4320

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

Answer & Explanation Answer: B) 169

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

Answer & Explanation Answer: A) 411

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

Answer & Explanation Answer: A) 62

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:

Next number in the given series is

9 7 10 6 11 ?

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

Answer & Explanation Answer: A) 5

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

Answer & Explanation Answer: 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.
