4.2,26.0,8.9,8.4,52.0,17.8,16.8,104 ?

• Ans. 35.6
  It is a question of multiple series.
  4.2*2=8.4*2=16.8

• by taking alternating series
  4.2*2=8.4 , 8.4*2=16.8......
  26.0*2=52 , 52.0*2=104..
  8.9*2=17.8 ,17.8*2=35.6..

• here we get 3 series ...first one is 8.9,17.8,...
  secound is 4.2,8.4,16.8,?
  third one is 26,52,104,...
  
  so, 4.2*2=8.4,
  8.4*2=16.8,
  16.8*2=33.6
  answer is 33.6

• 26.0*2=52.0
  52.0*2=104
  
  8.9*2=17.8
  8.4*2=16.8
  
  so
  17.8*2=35.6
  16.8*2=33.6
  will be nxt term

• Best Way
  
  first simply the terms by removing points.. 26.0 -> 26
  52.0 -> 52
  Now you will understand the similar terms in the series..and try checking with all the terms alternatively u will get the answer..
  8.9 * 2 = 17.8
  17.8 * 2 = 35.6

• Make series as three parts as 4.2,26.0,8.9 as 1 group
  8.4,52.0,178 as 1 group
  16.8,104 as 1 group
  Now multiply 4.2*2=8.4
  26.0*2=52.0...........
  17.8*2=35.6
