• 8,0.5,16,4,15,0.3,50,4.5,6,0.2,30,?
  8/0.5=16 and 8*0.5=4
  15/0.3=50 and 15*0.3=4.5
  6/0.2=30 and 6*0.2=1.2

  (0,1,1,2,0.5),(2,2,4,2,2),(4,3,7,2,?)
  0+1 = 1 , 1/2 =.5
  2+2 = 4 , 4/2 = 2
  4+3 = 7, 7/2 = 3.5

• 4)3/2, 9/4, 9/4, 7/2, 49/4, 49/4,
  sol:
  (3/2)^2=9/4
  (7/2)^2=49/4
  7/2-3/2=4/2 so
  7/2+4/2=11/2
  so 11/2 is the answer and 3/2,9/4,9/4,7/2,49/4,49/4,11/2,121/4,121/4 is the series

• 3.(8,5,9),(7,2,25),(5,1,16)(8,6,?)
  (8-5)^2=9
  (7-2)^2=25
  (5-1)^2=16
  (8-6)^2=4
  ans:4

• 2)(8,0.5,16,4),(15,0.3,50,4.5),(6,0.2,30,?)
  ans:
  8/16=0.5 8*0.5=4
  15/50=0.3 15*0.3-4.5
  6/30=0.2 6*0.2=1.2
  So 1.2 is answer
