16 is only one perfect square. Others are not a perfect square. So two answer for this question.

10, 14, 16, 18, 21, 24, 26

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.

21 is not an even number. So the odd man out is 21.

All are multiples of 2 except 21 so it is an odd number.

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.
