• ans is 3).17......all except 17 are squares of the natural nos. 1^2=1,2^2=4,3^2=9.......4 should have been 16.....so ans is 3)17

• the series is incorrect ..the correct is 5,1,2,8,1,0,9,3,2,14,1,3
  now add the 3 starting numbers we get 4th one
  like this 5+1+2=8
  after getting 8 we add the 3 numbers including 8
  like 8+1+0=9 and we get 7th number...and
  9+3+2=14,
  14+1+3=18
  so ANS=18
• 9 years agoHelpfull: Yes(3) No(3)
• ans: 5+3=8,
  8+1=9
  9+5=14,
