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 odd man out of the following number series?

22, 26, 42, 78, 142, 244

 A) 244 B) 142 C) 78 D) 42

Explanation:

The given number series 22, 26, 42, 78, 142, 244 follows a pattern that,

Hence, the odd one in the given number series is 244.

Q:

Find the next number in the given number series?

11, 5.5, 10, 6.5, 9, ?

 A) 6.5 B) 7.5 C) 8.5 D) 10.5

Explanation:

The given number series follows a pattern that

11

11 - 5.5 = 5.5

5.5 + 4.5 = 10

10 - 3.5 = 6.5

6.5 + 2.5 = 9

9 - 1.5 = 7.5

Hence, the next number in the given number series is 7.5.

Q:

Find the odd man out of the following number sequence?

3, 5, 13, 43, 167

 A) 167 B) 43 C) 13 D) 5

Explanation:

The given number series is 3, 5, 13, 43, 167

3

3 x 1 + 2 = 5

5 x 2 + 3 = 13

13 x 3 + 4 = 43

43 x 4 + 5 = 177 (not equal to 167)

Hence, the odd number in the given number sequence is 167.

Q:

Find the next number in the given number series?

35, 36, 55, 111, ?

 A) 278.5 B) 264.5 C) 212.5 D) 202

Explanation:

The given number series is 35, 36, 55, 111, ?

35

35 x 1 + 1 = 36

36 x 1.5 + 1 = 55

55 x 2 + 1 = 111

111 x 2.5 + 1 = 278.5

Hence, the next number in the given number series is 278.5.

Q:

What is the missing number in 5, 14, 42, 107, 233, ?

 A) 316 B) 384 C) 450 D) 479

Explanation:

Given Series is 5, 14, 42, 107, 233, _?

5, 14, 42, 107, 233, _?

Differences is 9, 28, 65, 126

9 = 2^3 + 1

28 = 3^3 + 1

65 = 4^3 + 1

126 = 5^3 + 1

Now, next difference must be 6^3 + 1 = 217

Hence, next number in the given series = 233 + 217 = 450.

Q:

Find the odd one out of the floowing number series?

270, 261, 279, 252, 289, 243

 A) 270 B) 279 C) 289 D) 243

Explanation:

Here the given number series is 270, 261, 279, 252, 289, 243

270 - 9 = 261

261 + 18 = 279

279 - 27 = 252

252 + 36 = 288 (not equals to 289)

288 - 45 = 243

Hence, the odd number in the given number series is 289.

Q:

Find the next number in the number series?

6, 6, 9, 18, 45, ?

 A) 87 B) 99.75 C) 115.5 D) 135

Explanation:

The given number series is 6, 6, 9, 18, 45, ?

Here the series follows a pattern that,

6 x 1 = 6

6 x 1.5 = 9

9 x 2 = 18

18 x 2.5 = 45

45 x 3 = 135

Hence, the next number in the given number series is 135.

Q:

Find the odd one out of the following number series?

56, 64, 48, 90, 16, 144

 A) 48 B) 64 C) 90 D) 16

Explanation:

The given number series follows a pattern that,

56

56 + 8 = 64

64 - 16 = 48

48 + 32 = 80 (Not equal to 90)

80 - 64 = 16

16 + 128 = 144

Hence, the odd number in the given number series is 90.
