8 * 1 = 8 - 2 = 6,
6 * 2 = 12 - 3 = 9,
9 * 3 = 27 - 4 = 23,
23 * 4 = 92 - 5 = 87,
87 * 5 = 435 - 6 = 429.
6 * 2 = 12 - 3 = 9,
9 * 3 = 27 - 4 = 23,
23 * 4 = 92 - 5 = 87,
87 * 5 = 435 - 6 = 429.

There is one thing here i want to mention where is 8.
if 8*1-2=6 so 8*0-1 =-1 but it doesn't match up.
and even i use 8*1-1 = 7 not 8.
if 8*1-2=6 so 8*0-1 =-1 but it doesn't match up.
and even i use 8*1-1 = 7 not 8.
