`Find the missing number in the following series? `

`3, 5, 5, 19, 7, 41, 9, ?`

A. 61

B. 69

C. 71

D. 79

**Answer: C. 71**

**Solution:**

**First series : 3, 5, 7, 9**

3,5,7,9,11,13,15,…. The difference between two consecutive numbers is 2.

**Second series : 5, 19, 41, ?**

14,22,30,… difference between two consecutive numbers is a multiple of 8.

Next term is 41 + 30 i.e equal to 71.

So, series will be 5,19,41,71,..…

**Hence, the answer is 71.**
