Find the next term in this series BY50, DW92, FU126, HS152

The pattern in the series seems to be as follows:

1. The first letter of each term decreases by 2 (B -> D -> F -> H -> ?).
2. The second letter of each term increases by 2 (Y -> W -> U -> S -> ?).
3. The number in each term increases by 34 (50 -> 92 -> 126 -> 152 -> ?).

So, the next term in the series should be:

1. The first letter after H (when decreasing by 2) is F.
2. The second letter after S (when increasing by 2) is U.
3. The number after 152 (when increasing by 34) is 186.

Therefore, the next term in the series is "FU186".
