  (round off)
  
  2)11.5,17.5,35.5,89.5.?
  Ans:
  11.5-17.5 = 6 = 3* (2*1)
  17.5-35.5 = 18 = 3*(2*3^1)
  25.5-89.5 = 54 = 3*(2*3^2)
  89.5-251.5 = 162 = 3*(2*3^3)
  ans : 251.5
  
  3)1/3,1/2,1/4,2 1/3,3 1/2,4 1/4,4 1/3 ,6 1/2,?
  Ans:
  Series like:(1/3, 2 1/3, 4 1/3),(1/2, 3 1/2 , 6 1/2),(1/4, 4 1/4 , ?)->ans will be 8 1/4 ,
  increases by 4.
  
  4)6.5,8,8,12,9.5,24,11,36,?
  Ans:
  look at the alternate series:
  6.5+1.5=8,
  8+1.5=9.5 ,
  9.5+1.5=11 ,
  11+1.5,=12.5.(Ans)
  
  5)198,194,184,168,146,?
  Ans:
  198-4=194,
  194-(4+6)=184,
  184-(4+6+6)=168,
  168-(4+6+6+6)=146
  146-(4+6+6+6+6)=118(Ans)
  
  6)30,28,25,20,34,28,?
  Ans:Look at the alternate series 30,25,34,? another series will be 28,20,28,20.....
  So now, 30-5=25
  25+9=34
  34-5=29(Ans)
  
  7)18,20,22,20,28,20,?
  Ans:Two series:18,22,28,? and another alternate series is 20,20,20....
  18+4=22
  22+6=28
  28+8=36(Ans)
  
  
  8)11,8,17,14,23,24,31,32,?
  Ans:
  Prime number series:11,13-5,17,19-5,23,29-5,31,37-5,41(Ans)

  Ans:
  9 + 3^2 = 18(next term)
  21 + 2^2 = 25
  20 + 1^2 = 21(Ans)
  
  
  10)1370,1320,1070,-180.?
  Ans:
  1370-50=1320,
  1320-(50*5)=1070,
  1070-(250*5)=-180,
  -180-(1250*5)=-6430(Ans)
