Q:

Please enter the Missing number: 4 8 14 22 ?

A) 28 B) 32
C) 46 D) 36
 
Answer & Explanation Answer: B) 32

Explanation:

Here the given series follows a pattern that,

2- 0 = 4  

3- 1 = 8  

4- 2 = 14

5- 3 = 22

6- 4 = 32

Hence, the missing number is 32

 

 

Method 2 ::

The difference between 4 and 8 is 4, the difference between 8 and 14 is 6, the difference between 14 and 22 is 8. So the next difference between 22 and the next number will be 10 since it follows (4,6,8,10 - add +2 each time)

Hence, 22 + 10 = 32 is the missing number.
