• (1.8,3,0.6),(2.5,5,0.5),(3.4,2,1.7) x
  
  2.5 - 0.6 = 1.9
  3.4 - 0.5 = 2.9
  x - 1.7 = 3.9
  x = 5.6
  
  Ans : 5.6

• correct series will be 1.8,3,0.6,2.5,5,0.5,3.4,2,1.7)
  
  (1.8,3,0.6), (2.5,5,0.5), (3.4,2,1.7), x
  1.8/3=0.6 2.5/5=0.5 3.4/2=1.7
  
  now 1.8+0.7=2.5, 2.5+0.9=3.4, similarly 3.4+1.1=4.5
  here the difference of 1st element of each group is in following pattern
  0.7,0.9(0.7+0.2), 1.1(0.9+0.2). so the answer is 4.5.

• (1.8,3,0.6) , (2.5,5,0.5) , (3.4,2,1.7) , x
  
  2.5 - 1.8 = .7
  3.4 - 2.5 = .9
  x - 3.4 = 1.1
  
  therefore x should be 4.5

• that series is not correct. small mistake is there
  the series will be like that
  1.8,3,0.6,2.5,3,0.5,3.4,2,1.7,....
  1.8/3=.6
  1.5/3=.5

• that series is not correct. small mistake is there
  the series will be like that
  1.8,3,0.6,2.5,5,0.5,3.4,2,1.7,....
  next term will be 4.5=(3.4+1.1)
  because look at the series u will find 2.5=1.8+0.7
  then 3.4=2.5+0.9
  then 3.4+1.1=4.5

• observe the alternate series
  3,2.5,0.5,2,?
  means 1st-3rd=2nd, 2nd-4th=3rd,
  similarly
  3rd-5th=4th
  i.e,
  0.5-?=2
  so, ?=0.5-2=-1.5
