• hai evry one i think sravya sree is correct...........70 is ans......
  
  @kodi..... we have to consider all the sequence leaving some values as our wish will result in mistake i think........
  
  @bhowmik......u had taken 71 but its given 75 not 71 check it plz...........
  
  @baidyanath...... in your solution u had done many mistakes plz chexk it out...... 6+17+14=35 which is wrong =37.... and 14+35+31=75 is also wrong =80....
  if its had given 61 insted of 75 then that approach will be some wht f9 and it may give 66 as result...........but for now i conclude that 70 will be final...........

• Ans. 66
  There are two series, the one with missing term is:
  6 14 31 '66'
  This is how:
  6
  6*2 +2=14
  14*2+3=31
  31*2+4=66

• 8+(8+1)=17
  17+(17+1)=35
  35+(35+1)=71...
  (6*2)+2=14
  (14*2)+3=31
  (31*2)+4=66.
