• 3/2, (3^2/2^2=9/4) and 9/4 is then written as 2 1/4.
  Therefore for 8/3 the next term will be 7 1/9 which is equal to 8^2/3^2 and the next term will be 64/9
  answer is 7 1/9

  now (16,26) , (9,19) , (65,75) have difference of 10
  also new these sets are coming in periodic gap of one fraction number .
  new series obtained will be
  
  (16,26) , (9,19) , (65,75)
  16-9= 7 (decreasing)
  26-19=7 (decreasing).. 7 is the gap so ,
  
  65 -7 = 58
  75-7= 68
  
  Hence the number is 58

  1. 33+8=41
  similarly add n get third number.. 46+21=67
  72+47=119
  124 +y = a... let it be y and a.. the next two terms..
  
  2. take difference of the results got in 1.
  like 67-41=26 i.e. 26*1
  119-67=52 i.e. 26*2
  similarly next difference wud be 26*3=78...
  so a-119=78...
  
  now add and get a= 119+78=197
  
  now y will be 197-124=73..
  
  
  so series wud be 33,8,41,46,21,67,72,47,119,124,73,197

  now if u consider 2nd,5th,8th and so on then we will get 8,21,47.. look diff between those no is multiple of 13 so we can add 47+13*3=46 so the answer 86 so series will be 8,2147,86
  then the final series will be
  33,8,41,46,21,67,72,47,119,124,86,210 and so on... 86 is the ans
