• Focus on the elements 1, 2 and 3 first:
  28 14 15
  28 * 0.5 = 14
  14 + 1 = 15
  
  Now focus on elements 3, 4 and 5.
  15 22.5 24.5
  15 * 1.5 = 22.5
  22.5 + 2 = 24.5
  
  We multiple the elements at even slots with 0.5, 1.5, 2.5, 3.5 ... and add 1, 2, 3, 4, .... to the elements at odd slots.
  
  24.5 * 2.5 = 61.25
  61.25 + 3 = 64.25
  64.25 * 3.5 = 224.875
  
  The answer is 225.875.

• Multiply each number after 1's gap with the sequence of (0.5, 1+.05 , 2+0.5 , 3+0.5 , 4+0.5........................................)
  28*0.5=14
  15*1.5=22.5
  24.5*2.5=61.25
  64.25*3.5=224.875 ans.
