8,0.5,16,4,15,0.3,50,4.5,6,0.23,30,?

• 1.2
  
  Rewrite this into groups of four i.e.
  (8 , 0.5 , 16 , 4) , (15 , 0.3 , 50 , 4.5) , ( 6 , 0.2 , 30 , x )
  
  1st term = ( 8 , 0.5 , 8 / 0.5 , 8*0.5 )
  2nd term = ( 15 , 0.3 , 15 / 0.3 , 15*0.3 )
  3rd term = ( 6 , 0.2 , 6 / 0.2 , 6*0.2 )
  => x = 6 * 0.2 = 1.2

• 8*0.5=4
  15*0.3=4.5
  hence 6*0.23=1.38
  ans 1.38

• correct series is replace 0.23--->0.2(we will take )
  
  write this into 4 groups of number i.e.
  (8 , 0.5 , 16 , 4) , (15 , 0.3 , 50 , 4.5) , ( 6 , 0.2 , 30 , x )
  first divide and multiply
  
  1st term = 8 / 0.5=16 , 8*0.5 = 4
  2nd term = 15 / 0.3 =50 , 15*0.3 = 4.5
  3rd term = 6 / 0.2 = 30 , 6*0.2 = 1.2
  => x = 6 * 0.2 = 1.2
