Observe the pattern:
- The first part of the sequence increases by 1 (B, D, H, F...).
- The second part of the sequence (number) increases by 1 each time (2, 3, 5...).
- The last part is a 3-letter sequence that keeps moving alphabetically (CD, E3F, etc.).
So, the next term is: G3HI.
\(⇒\) \boxed{\text{G3HI}}
