AZA, BWD, CRI, DKP, __________.

Correct option is C

Given:

The series is: AZA, BWD, CRI, DKP, ________.
We observe patterns for the 1st, 2nd, and 3rd letters.

Formula Used:

1. First Letter: Increases alphabetically by 1 in each step.
2. Second Letter: Moves backward in the alphabet by a specific sequence.
3. Third Letter: Moves forward in the alphabet by a specific sequence.

Solution:

1. First Letter:
• A→B→C→D→E
• The first letter in the missing term is E.
2. Second Letter:
• Z→W→R→K→B (Follows the sequence of -3, -5, -7, -9).
• The second letter in the missing term is B.
3. Third Letter:
• A→D→I→P→Y (Follows the sequence of +3, +5, +7, +9).
• The third letter in the missing term is Y.

Thus, the missing term is EBY.
