F again, maybe? I'm thinking assigning numbers to the letters, with A=1 and B=2, we get
T = 20
with each letter being the difference between the previous two letters. So the sequence starting with FT would be:
F(6) T(20) N(14) F(6) H(8) B(2) F(6) D(4) B(2) B(2)... and I guess that's it.
Probably wrong, but it sort of made sense
