Q. What is the next number of the following sequences
1) 1,1/2,3/2,2,5,1/3,16/3,15,12,1/4,49/4,7,?
2) 2,1,3,4,3,5,6,5,7,8,?
3) 6,9,18,6,36,3,54,?
4) 6.5,8,8,12,9.5,24,11,36
5) 7/6,3/2,11/6,13/6,5/2,?
6) 2,5,9,1,5,10,3,8,?
7) 63/4,16,26,46/5,9,19,194/3,65,75,243/8,?
8) 4,2,4,8,6,8,16,?
9) 5,6,6.5,6.5,8,7,9.5,?
10) 9,15,26/3,29/2,25/3,14,8,27/2,?
11) 1,2,3,6,11,20,37,68,?
12) 1,1,1,2,2,2,3,4,3,3,5,6,?
14) 11,8,17,14,23,24,31,32,?
15) 41.45,41.5,42,18.23,18.2,18,?

• 2)2,1,3,4,3,5,6,5,7,8,?
  make group of three and rearrange as shown below
  2,1,3---> 1,2,3
  4,3,5---> 3,4,5
  6,5,7---> 5,6,7
  8,7,9---> 7,8,9
  so ans is 7
  3) 6,9,18,6,36,3,54,?
  considering alternate numbers or the numbers at odd positions
  6,18,36,54
  6*1=6
  6*3=18
  6*6=36
  6*9=54
  now,considering alternate numbers or the numbers at even positions
  9,6,3
  3*3=9
  3*2=6
  3*1=3
  next 3*0=0
  so, ans is 0
  4)6.5, 8, 8, 12, 9.5, 24, 11, 36
  considering values at odd positions
  6.5,8,9.5,11
  6.5+1.5=8
  8+1.5=9.5
  9.5+1.5=11
  next, 11+1.5=12.5
  so ans is 12.5
  8) 4,2,4,8,6,8,16,?
  series is like
  4, ... 2,4, ... 8, ...6,8,... 16
  clearly,
  2+2=4
  4+2=6
  6+2=8... and so on
  and
  4*2=8
  8*2=16
  so answer is
  16*2=32

• 2)Given series is {2},[1],3,{4},[3],5,{6},[5],7,{8},[7=ans],9,{10}
  it is combination of three series 2,4,6,8:
  1,3,5,(7=ans):3,5,7,9
  three series differentiated by different brackects

• 5)series is 7/6,9/6,11/6,13/6,15/6 so the next no is 17/6=ans
  9)its combination of two series 5,6.5,8,9.5 and 6,6.5,7,7.5=ans
  12)its combination of 3 series [1],{1},1,[2],{2},2,[3],{4},3,[3],{5},6
  one series is 1,2,3,3,6=ans,9
  second series is 1,2,(3:skipped)4,5,(6:skipped)7,8....
  third series is 1,2,3,(skip 4,5),6,7,8,(skip 9,10)...
  the whole series may continue as 1,1,1,2,2,2,3,4,3,3,5,6,{6,7,7...
  14)[11],8,[17],14,[23],24,[31],32 is divided in to 2 series as
  first series is 11,11+6,17+6,23+8,31+8=ans
  second series is 3^2-1,4^2-2,5^2-1,6^2-4,7^2-1,8^2-6

• 2) 2,1,3,4,3,5,6,5,7,8
  first make a group of 3 numbers 2 1 3
  4 3 5
  6 5 7
  8 9 9
  so ans will be 9

• 6) make set of three
  2,2+3=5,5+4=9,
  1,1+4=5,5+5=10,
  3,3+5=8,8+6=14
