Here the logic is :

5*2 = 10

7*2 = 14

8*2 = 16...& so on

So where is 6*2 ??????

21is the correct answer because all the other numbers can be perfectly divided by 2

Here the logic is :

5*2 = 10

7*2 = 14

8*2 = 16...& so on

there for 21 is the right answer...

5*2 = 10

7*2 = 14

8*2 = 16...& so on

there for 21 is the right answer...

For 24, karthik's logic is not valid. For this case the difference is also odd. Thus the logic given by karthik is wrong.

The difference between adjacent numbers is even. But for 21 it is not true.

Hence the answer is 21.

Hence the answer is 21.
