• its quite easy
  consider the alternate numbers i.e,odd places 1 2 8 8 4 4 ...
  the other alternate numbers i., even places 2 4 1 0.5 1 4 ..
  now by multiplying the first number of odd place with first number of even we get the next number of odd place
  1*2=2
  2*4=8
  8*1=8
  8*0.5=4
  4*1=4
  finally 4*4=16

• (1,2,2,4,8) => 1*2 = 2, 2*4 = 8 Product of 1st 2 numbers is the 3rd number
  (8,1,8,1/2,4) => 8*1 =8, 8*1/2 = 4
  (4,1,4,4,16) => 4*1 = 4, 4*4 = 16
