I believe that the answer is
L
This is based on the fact that the first and last letters of each triplet is the same. For example,HAH
,LUL
, etc...
This is my random solution

The answer is:
W
Sequence is
8, 1, 8, 12, 21
- ignoring the first as red herring, the distance between each value is[7,4,9]
(for example, 8 - 1 = 7, 12 - 8 = 4, etc.). The distance between those values shows a growing sequence of odd, prime numbers: [3,5] (for example, 7-4 = 3, 9-4 = 5).
However, it seems it oscillates between subtraction and addition. 7 - 4 = 3, but 4 + 5 = 9. I'd assume the next sequence would be
7
, which is an odd prime number. And the next step requires subtraction, so it is: 9 - 7 = 2. Therefore, the next number would jump by 2 units (21 + 2). Which ends up in 23, which is the letterW
