- 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
