Ans:20
The other numbers are formed by :
2x2=4
2x2x2=8
2x2x2x2=16
But,20 is formed as follows:
2x2x5=20
Hence, my answer is 20.

Reason:
All the other numbers, 16,8,20 and 4 are all multiples of four. However, 2 is not able to be multiplied by 4. Therefore, 2 is the odd one out.

DANA said...

20 is a possible answer as well.

Anonymous said...

2.all the other numbers can be divided by 4 but 2 cannot

Anonymous said...

Dana, you are right.

While 2^1=2, 2^2=4, 2^3=8 and 2^4=16, 2^5=32. Therefore, 20 may be the odd-one out.

2 is also a possible answer, since 4, 8, 16 and 20 are divisible by 4, but not 2.
