Q:

What value will come in place of question mark (?) in the number - series given below  ? 

4, 30, ?, 1440, 7195, 71940

A) 145 B) 545
C) 650 D) 999

Answer:   A) 145



Explanation:

4       30       ?     1440       7195      71940

 

Here the given series follows a pattern of

 

4

 

4 x 10 - 10 = 30

 

30 x 5 - 5  = 145

 

145 x 10 - 10 = 1440

 

1440 x 5 - 5 = 7195

 

7195 x 10 - 10 = 71940

 

Hence, the missing number is 145
