Q:

# Find out the wrong number in the given sequence of numbers.52, 51, 48, 43, 34, 27, 16

 A) 27 B) 34 C) 43 D) 48

Explanation:

Subtract 1, 3, 5, 7, 9, 11 from successive numbers.

So, 34 is wrong.

Q:

Find the next number in the sequence?

28, 16, 28, 76, 274

 A) 1233 B) 1243 C) 1256 D) 1276

Explanation:

Given number sequence is 28, 16, 28, 76, 274

Here the sequence follows a pattern that

28

28 x 0.5 + 2 = 14 + 2 = 16

16 x 1.5 + 4 = 24 + 4 = 28

28 x 2.5 + 6 = 70 + 6 = 76

76 x 3.5 + 8 = 266 + 8 = 274

274 x 4.5 + 10 = 1233 + 10 = 1243

Hence, the next number in the given number sequence is 1243.

Q:

Find the odd one out?

6, 3, 3, 4.5, 10

 A) 3 B) 4.5 C) 6 D) 10

Explanation:

Here the given number series is 6, 3, 3, 4.5, 10

The odd one in the given series is 10

The pattern it follows is

6

6 x 0.5 = 3

3 x  1  = 3

3 x 1.5 = 4.5

4.5 x 2 = 9

Hence, the odd number is 10.

Q:

Which is the next number in the sequence:

1, 3, 6, 11, 20, 37, ??

 A) 49 B) 56 C) 64 D) 70

Explanation:

Here the given series is 1, 3, 6, 11, 20, 37, ??,

and the logic behind the series is

1 x 2 + 1 = 3

3 x 2 + 0 = 6

6 x 2 + (-1) = 11

11 x 2 + (-2) = 20

20 x 2 + (-3) = 37

37 x 2 + (-4) = 70

Hence, the next number in the given series is 70.

0 71
Q:

What is the next number in the following number series

3, 5, 8, 15, 28, 51, ?

 A) 98 B) 102 C) 87 D) 79

Explanation:

The given number series is

3, 5, 8, 15, 28, 51, ?

Here the pattern it follows is

3

3 + 2 = 5 ( add prime number less than 3 i.e, 2)

5 + 3 = 8 (3 is prime number less than 5)

8 + 7 = 15 (7 is prime number less than 8)

15 + 13 = 28 (13 is prime number less than 15)

28 + 23 = 51 (23 is prime number less than 28)

51 + 47 = 98 (47 is prime number less than 51)

Hence, the next number in the given number series is 98.

Q:

Find the missing number in the given number series?

2676, 445, ?, 21,6, 2, 1

 A) 88 B) 92 C) 96 D) 102

Explanation:

The given number series 2676, 445, ?, 21,6, 2, 1 follows a pattern that,

From right side,

1

1 x 1 + 1 = 2

2 x 2 + 2 = 6

6 x 3 + 3 = 21

21 x 4 + 4 = 88

88 x 5 + 5 = 445

445 x 6 + 6 = 2676

Hence the missing number in the given number series is 88.

Q:

Find the next number in the given number series?

2, 19, 0, 21, –2, ?

 A) 23 B) 25 C) 27 D) 29

Explanation:

The given number series 2, 19, 0, 21, –2, ? follows a pattern,

2

2 + 17 = 19

19 - 19 = 0

0 + 21 = 21

21 - 23 = -2

-2 + 25 = 23

Hence, the next number in the series is 23.

0 81
Q:

Find the next number in the given number series?

3, 10.5, 36.75, 128.625, ?

 A) 295.651 B) 354.146 C) 398.78 D) 450.187

Explanation:

Here the given number series  3, 10.5, 36.75, 128.625, ? follows a pattern that

3

3 x 3.5 = 10.5

10.5 x 3.5 = 36.75

36.75 x 3.5 = 128.625

128.625 x 3.5 = 450.187

Hence the next number in the given number series is 450.187.

Q:

What number should replace the question mark?

125, 138, 164, ?, 255

 A) 189 B) 197 C) 200 D) 203

Explanation:

The given number series is 125,   138,   164,   ?,   255

125

125 + 13x1 = 138

138 + 13x2 = 164

164 + 13x3 = 203

203 + 13x4 = 255

Hence, the missing number in the series is 203.
