Show answer & explanation

Correct answer: A

Key idea: the two letters in each term follow separate increasing-step patterns.

  • First letters: A (1), C (3), F (6), J (10). Differences are +2, +3, +4, so the next difference is +5: 10 + 5 = 15 → O.

  • Second letters: D (4), G (7), K (11), P (16). Differences are +3, +4, +5, so the next difference is +6: 16 + 6 = 22 → V.

  • Combine them: the next term is OV.
