There are two series. Both series increments by 1.
At ODD place (start with 8) : 8, 9, 10, 11, 12,....and so on.
At EVEN place (start with 12) : 12, 13, 14, 11, 15,....and so on.

8 + 4 = 12,
12 - 3 = 9,
9 + 4 = 13,
13 - 3 = 0,
10 + 4 = 14,
14 - 3 = 11,
11 + 4 = 15,
15 - 3 = 12.
12 - 3 = 9,
9 + 4 = 13,
13 - 3 = 0,
10 + 4 = 14,
14 - 3 = 11,
11 + 4 = 15,
15 - 3 = 12.
