Except 21 all are even. So I do think Shraddha's logic is wrong and no need to think about because the answer of this is in simple logic. Karthik don't you think that you need not go so deep?

another method in my view is :-

10 = 2 * 5

14 = 2 * 7

16 = 2 * 8

18 = 2 * 9

21 = (21 is not multiply by 2 with any number).

24 = 2 * 12

26 = 2 * 13.

There are 2 possibilities.

All the numbers are multiples of 3 except 26. So 26 is the odd man out.

All the numbers can be divided by 2 except 21. So, it is odd one.

Added the numbers to previous numbers

4,2,2

and

4,2,2

That format in the 21 place we get the 20 only.

That's why 21 is odd man out.

4,2,2

and

4,2,2

That format in the 21 place we get the 20 only.

That's why 21 is odd man out.

I agree with @Bala krishnan even I thought the same. In table of 3 the numbers follows. 3x6=18, 3x7=21, 3x8=24. So A26 is oddman out.

5*2=10.

7*2=14.

8*2=16.

9*2=18.

11*2=22.

12*2=24.

Here you observe that 11*2=22, but in quest it was given 21. So the answer is 21.

7*2=14.

8*2=16.

9*2=18.

11*2=22.

12*2=24.

Here you observe that 11*2=22, but in quest it was given 21. So the answer is 21.

@shraddha your logic is wrong

as u said

Here the logic is :

5*2 = 10

7*2 = 14

8*2 = 16...& so on

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

5*2 = 10

8*2 = 16...& so on

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

10+4=14

14+2=16

16+2=18

Again the number 18 is added with 4

18+4=22

22+2=24

24+2=26

So we will add 4,2,2,4,2,2

14+2=16

16+2=18

Again the number 18 is added with 4

18+4=22

22+2=24

24+2=26

So we will add 4,2,2,4,2,2

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

Hence the answer is 21.

Hence the answer is 21.
