Question

Which of the following options should come in place of the ‘?’ in the given series based on the English alphabetical order? G 5, M 12, S 19, Y 26, ?

1. A. D 33
2. B. J 33
3. C. A 33
4. D. E 33 (Correct answer)

Correct Answer

Option D — E 33

Detailed Solution & Explanation

The correct answer is E 33.

Key Points

• Treat the letters and numbers as two separate sequences.
• Letters: G(7) → M(13) → S(19) → Y(25), each +6. The next is $25 + 6 = 31$, which exceeds 26, so wrap around: $31 - 26 = 5 = \textbf{E}$.
• Numbers: 5 → 12 → 19 → 26, each +7. The next is $26 + 7 = \textbf{33}$.
• Combining gives E 33.

Additional Information

• The wrap-around is the whole difficulty. Treating the alphabet as circular — after Z comes A again — is what produces E; stopping at Z gives no valid option, and the distractors A 33, D 33 and J 33 correspond to different miscounts of the wrap.
• Note the two increments differ: letters advance by 6 and numbers by 7. Assuming a single shared step is a natural but wrong instinct.
• The formula for wrapping is $((\text{position} - 1) \bmod 26) + 1$, which handles any number of loops around the alphabet.
• Since all four options share the number 33, the number sequence alone cannot decide the answer — the letter is the entire test, and the arithmetic must be done rather than estimated.
