What value will come in place of question mark (?) in the number - series given below ? 4, 30, ?, 1440, 7195, 71940

Correct Answer: 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
