Answer 1

Correct Answer - Option 3 :

13, 2

The given number series:

 3, 5, 7, 9, 11, ?

 2, 2, 2, 2, 2, ?

Logic :

In the first row, Next Number = Previous Number + 2 

while in the second row all the numbers are same i.e. 2.

so for first row

 ⇒ 3 + 2 = 5

 ⇒ 5 + 2 = 7

 ⇒ 7 + 2 = 9

 ⇒ 9 + 2 = 11

 ⇒ 11 + 2 = 13

the next number in the second row will be 2..

 3, 5, 7, 9, 11, 13

 2, 2, 2, 2, 2, 2

Hence, 13, 2  is the correct answer.
