What is the next number of the following sequence

1) 8 0.5 16 4 15 0.3 50 4.5 0.2 30 ?

2) 5/6,1/3,1/2,1/2,2/8,1/4,5/6,1/6,2/3,1/2,1/3,?

• 1) 8 0.5 16 4 15 0.3 50 4.5 0.2 30 ?
  (8,0.5,16,4),(15,0.3,50,4.5),(6,0.2,30, X )
  
  8/0.5=16 , 8*0.5=4
  15/0.3=50, 15*0.3=4.5
  6/0.2=30, 6*0.2 =1.2 => x=1.2
  
  2) 5/6,1/3,1/2,1/2,2/8,1/4,5/6,1/6,2/3,1/2,1/3,?
  (5/6,1/3,1/2),(1/2,2/8,1/4),(5/6,1/6,2/3),(1/2,1/3,x)
  
  5/6 = 1/3 + 1/2
  1/2 = 2/8 + 1/4
  5/6 = 1/6 + 2/3
  1/2 = 1/3 + x => x=(1/2 - 1/3)= 1/6
