B1A, D8E, F27I, ______, J125Q

The missing term in the sequence is: H64L

Detailed Explanation:

The given sequence is: B1A, D8E, F27I, ______, J125Q

• In this sequence, the pattern follows three components in each term: Letter1 Number1 Letter2.
• The first letter (Letter1) in each term increases by 2 positions in the alphabet each time:
  • B → D → F → H → J (This is a +2 step in the alphabet each time).
• The number (Number1) increases by 7 at each step:
  • 1 → 8 → 27 → 64 → 125 (This is a +7, then +19, then +37, then +61 increment).
• The second letter (Letter2) increases by 3 positions in the alphabet:
  • A → E → I → L → Q (This is a +3 step in the alphabet each time).

Thus, the missing term is H64L as it follows the patterns for both the letters and numbers.

Concept

• Letters and numbers follow specific patterns, such as increments in alphabet position and numerical values.
• The first letter increases by 2, the number increases by a growing step (7, then 19, etc.), and the second letter increases by 3 positions.
• By identifying these patterns, we can predict the missing term in the sequence.
