9. 

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

[A]. 26[B]. 24
[C]. 21[D]. 18

Answer: Option B

Explanation:

Each of the numbers except 21 is an even number.

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

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

@ karthik
here even doesn't mean difference b/w numbers but except 21 rest numbers are even..

21 is odd man out

Here the logic is :
5*2 = 10
7*2 = 14
8*2 = 16...& so on
there for 21 is the right answer...

Linta&Amp;Sruthy said: (Tue, Jun 28, 2011 02:43:34 AM)    
 
21is the correct answer because all the other numbers can be perfectly divided by 2

@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 ??????

@shradda.

There is no term for 6*2 &also it doesnot match for 11*2.
