• The Answer is 21
  The series consists of two series:
  3,11,17 and 5,14,21( In each series the difference of successive term is reduced by two). Thus the next term would be 17+4=21

• the ans is 21
  consider alternate terms, the series are: 3, 11, 17,- and 5, 14, 21,-
  now see the differences between consecutive terms that is decresing by 2 each time.
  the first series will be like:
  3+8=11, 11+(8-2)=17, 17+(8-2-2)=21, 21+(8-2-2-2)=23,and so on..
  and the second series will be like:
  5+9=14, 14+(9-2)=21, 21+(9-2-2)=26, 26+(9-2-2-2)=29,and so on..
  
  hence the combined series will become 3, 5, 11, 14, 17, 21, 21, 26, 23, 29...
  so the answer 21.

• 14 because it is even and rest are odd ones

• Answer is A.
  
  11-3=8
  17-11=6 This is the first series.
  
  14-5=9
  21-14=7 This is the second series.
  
  Required answer is 17+4=21

• A)21
  difference between 3&11 is 8,5& 14 is 9,11&17 is 6 ,14 &21 is 7
  so we get new sequence as 8,9,6,7,4
  so 4+17=21

• Answer is C. Remaining Numbers are ODD numbers

• 14
  all other are odd

• 21
  there are two series
  3,11,17....(difference is 8,6,next is 4 increment gives)>>21
  5,14,21.....
• 12 years agoHelpfull: Yes(0) No(0)
• answer:21 because first series:3,11,17,?
  second series:5,14,21
  in first series difference is 8,6,4 so answerr is 21

• i think it is 14.
  clearly watching that only 14 is even.
  so (C).14 is the answer.
