Answer 1

Answer:

The missing number in the series 3,5,9,11,?,33,65 will be 17.

Step-by-step explanation:

On multiplying 2 each number of the series and after that subtracting 1 of found number, then the resultant number will be next number.

e.i. on multiplying 2 and after that subtracting 1, result will be next number.

2x2 = 4-1 = 3

similar,

on multiplying 2 and after that subtracting 1

3x2 = 6-1 = 5

similarly,

5x2 = 10-1 = 9

similarly,

9x2 = 18-1 = 17

similarly,

17x2 = 34-1 = 33

similarly,

33x2 = 66-1 = 65

Therefore, the complete series will be 3, 5, 9, 11, 17, 33, 65

So, The missing number in the series 3,5,9,11,?,33,65 will be 17.
