Q:

# Find the missing number?15, 30, ? , 40, 8, 48

 A) 21 B) 8 C) 19 D) 10

Explanation:

Given nuber series is 15, 30, ? , 40, 8, 48

Here the number series follows a pattern that

15

15 x 2 = 30

30 $÷$ 3 = 10

10 x 4 = 40

40 $÷$ 5 = 8

8 x 6 = 48

Hence, the missing number in the series is 10.

Q:

Find the odd man out?

12, 48, 168, 502, 1260

 A) 48 B) 168 C) 502 D) 1260

Explanation:

The given series is 12, 48, 168, 502, 1260

12

12 x 4 = 48

48 x 3.5 = 168

168 x 3 = 504

504 x 2.5 = 1260

Hence, the odd man out in the given series is 502.

Q:

Find the odd man out of the following number series?

222, 271, 308, 332, 348, 357

 A) 271 B) 308 C) 332 D) 348

Explanation:

Here the given series 222, 271, 308, 332, 348, 357 follows a pattern that

222

222 + 49  271

271 + 36 = 307 (NOT 308)

307 + 25 = 332

332 + 16 = 348

348 + 9 = 357

Hence, the odd man in the fiven number series is 308.

Q:

Find the odd man out?

28, 12, 4, 2, -2

 A) -2 B) 2 C) 12 D) 28

Explanation:

Here the given series 28, 12, 4, 2, -2 follows a pattern that

Hence, the odd man in the given series is 2.

Q:

Find the odd man out of the following number series?

1/2, 1, 3/2, 6, 5/2, 3

 A) 1 B) 6 C) 5/2 D) 3/2

Explanation:

The given series is 1/2, 1, 3/2, 6, 5/2, 3

1/2

1/2 + 1/2 = 1

1 + 1/2 = 3/2

3/2 + 1/2 = 2 (Not 6)

2 + 1/2 = 5/2

5/2 + 1/2 = 3

Hence, the odd man in the given number series is 6.

Q:

Find the odd man out of the series?

128, 32, 14, 2.66, 0.88

 A) 32 B) 14 C) 2.66 D) 0.88

Explanation:

Here the given series is 128, 32, 14, 2.66, 0.88

128 / 4 = 32

32 / 3 = 10.666

10.666 / 4 = 2.666

2.666 / 3 = 0.888

Hence, the odd man in the given number series is 14.

Q:

Find the odd man out of the following number series?

720, 732, 708, 742, 696

 A) 696 B) 742 C) 708 D) 732

Explanation:

The given number series is 720, 732, 708, 742, 696

720

720 + 12 = 732

732 - 24 = 708

708 + 36 = 744 (Not 742)

744 - 48 = 696

Hence, the odd man in the given number series is 742.

Q:

Odd man out of the series

90 72 56 42 36 20

 A) 20 B) 36 C) 42 D) 56

Explanation:

The given number series is 90 72 56 42 36 20

9 x 10 = 90

8 x 9 = 72

7 x 8 = 56

6 x 7 = 42

5 x 6 = 30 (not 36)

4 x 5 = 20

Hence, the odd man in the given number series is 36.

Q:

Pick the odd man out of the folowing number sequence?

123 112 133 112 143

 A) 143 B) 122 C) 133 D) 112

Explanation:

Here the given series is 123 112 133 112 143

It follows a pattern that,

123

123 - 11 = 112

112 + 21 = 133

133 - 31 = 102 (not 122)

102 + 41 = 143

Hence, the odd man in the given number sequence is 122 instead of 102.
