Track the +3 jump for the first letter of each group and the +2 internal step for subsequent letters.
Analyze First Letters
Look at the first letter of each term: B (2), E (5), H (8), K (11). Each increases by +3. The next first letter is K + 3 = 14, which is N.
Analyze Internal Patterns
Within each triplet, letters advance by +2 (e.g., B to D is +2, D to F is +2; K to M is +2, M to O is +2).
Determine Final Term
Starting with N, add +2 to get P, and add +2 to P to get R, resulting in NPR.
B: NPQ ends with Q instead of R. C: NPS ends with S instead of R. D: MQS starts with M instead of N.
A is correct because the series progresses with a +3 shift for the starting letters and +2 internal increments, yielding NPR.
