what is the missing number in the sequence given below? 12 9 13.50 30.37 ? 341.71

Correct Answer: 67

Explanation:

Here the given number series is 3, 14, 36, 67, 113, 168

It follows a pattern that

3

3 + 1 x 11 = 3 + 11 = 14

14 + 2 x 11 = 14 + 22 = 36

36 + 3 x 11 = 36 + 33 = 69

69 + 4 x 11 = 69 + 44 = 113

113 + 5 x 11 = 113 + 55 = 168

 

Hence, the wrong number is 67.

Correct Answer: 29

Explanation:

The Given number series 3, 6.5, 14, 29, 64, 136 follows a pattern that

3

3 x 2 + 0.5 = 6.5

6.5 x 2 + 1 = 14

14 x 2 + 2 = 30  ?29

30 x 2 + 4 = 64

64 x 2 + 8 = 136

Thus the wrong number in the series is 29

Correct Answer: 75

Explanation:

Here in the given series, it follows a pattern that

 

77 + 2 = 79

 

79  - 3 = 76

 

76 + 5 = 81

 

81 -  7 = 74

 

74 + 11 = 85

 

Consecutive adding and subtracting of prime numbers.

 

So the wrong number in the given series is 75.

Correct Answer: 18.5

Explanation:

The given series pattern follows

 

17       9       10       18.5       35       90

 

× 0.5 + 0.5,   × 1 + 1,   × 1.5 + 1.5,   × 2 + 2,   × 2.5 + 2.5

 

So here 

 

17x0.5 + 0.5 = 9

 

9x1 + 1 = 10

 

10x1.5 + 1.5 = 16.5

 

16.5x2 + 2 = 35

 

35x2.5 + 2.5 = 90

 

Here the odd man in the given series is 18.5

Correct Answer: 44

Explanation:

  4             3             4             7               15        ?
×1-1      ×1+1       ×2-1       ×2+1           ×3-1

 

15x3 - 1 = 45 - 1 = 44

Correct Answer: 256 & 3125

Explanation:

The above given sequence follows a pattern that,

 

$$\begin{gathered} 1 \\ 2 2 = 4 \\ 3 3 = 27 \\ 4 4 = 256 \\ 5 5 = 3125 \\ 6 6 = 46656 \\ and so on . . . \end{gathered}$$

Therefore, the next two numbers in the given sequence is 256 & 3125.

Correct Answer: 36 & 90

Explanation:

the next 2 number in series we need to divide the series into 2 different series

First series : 4 , 6, 12, 30 ??

Second Series : 12,18,26, ??

So we need to see for the pattern for those series in order to find the next two number , we can do this by finding the difference or division , multiplication logic whatever may apply :

 

• Pattern of Series 1 :

 

6 divide 4 : 1.5

Next number i.e 12 divided by 6=2

Next number i.e 30 divided by 12 =2.5

So series is going in multiples of 1.5, 2, 2.5, 3 , so on

So first series will look like

4 , 6, 12, 30, 30x3 =90

 

• Pattern of Series 2 : 12,18,26, ??

 

Its simple Adding numbers with iterative logic (i.e 6, 8, then followed by 10, 12)

Series will be like 12,18,26,36.

 

For the next two numbers : Series will be like 4, 12, 6, 18, 12, 26, 30, 36, 90

Correct Answer: 21, 15, 23

Explanation:

Given number series is 9 17 11 19 13 

Here the pattern is

• 9

• 9 + 8 = 17

• 17 - 6 = 11

• 11 + 8 = 19

• 19 - 6 = 13

• 13 + 8 = 21

• 21 - 6 = 15

• 15 + 8 = 23

Correct Answer: 165

Explanation:

The given series follow the rule that :

Multiplying consecutive prime numbers
2,3,5,7,11,13,17,19....
2x3 = 6
3x5 = 15
5x7 = 35
7x11 = 77
11x13 = 143
13x17 = 221
So, the wrong term is 165.

Correct Answer: 80

Explanation:

There should be 90 instead of 80
so we can have a series
5, 5x3, 15x2, 30x3, 90x2, 180x3, 540x2 and 1080x3 and so on...
