Q:

What will come in place of the question mark (?) in the following number series  ?

12, 24, 26.5, 79.5, ?, 330

A) 211 B) 101.5
C) 82.5 D) 99

Answer:   C) 82.5



Explanation:

The given series 

 

12   24   26.5   79.5   ?   330 follows a pattern that,

 

12 x 2 = 24

 

24 + 2.5 = 26.5

 

26.5 x 3 = 79.5

 

79.5 + 3 = 82.5

 

82.5 x 4 = 330

 

Hence, the missing number is 82.5

Q:

Find the wrong number in the given number series?

10, 21, 54, 109, 189

A) 189 B) 109
C) 54 D) 21
 
Answer & Explanation Answer: A) 189

Explanation:

The given number series is 10, 21, 54, 109, 189

The series follows a pattern that

10 + 11 = 21

21 + 33 = 54

54 + 55 = 109

109 + 77 = 186

 

Hence the wrong number in the given number series is 189.

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.

A) 167 B) 43
C) 13 D) 5
 
Answer & Explanation Answer: A) 167

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.

35, 36, 55, 111, ?

A) 278.5 B) 264.5
C) 212.5 D) 202
 
Answer & Explanation Answer: A) 278.5

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
 
Answer & Explanation Answer: C) 450

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
 
Answer & Explanation Answer: C) 289

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.
