Solve this Alphabetical Series question: Find the next letter in the series: E, F, I, N, U, D, ?
Explanation
The verified answer to “Solve this Alphabetical Series question: Find the next letter in the series: E, F, I, N, U, D, ?” is O, option B. Convert every letter to its alphabet position and inspect all transitions. The sixth known letter is D; applying the next required movement gives O. To solve reliably, represent every term, person, seat, letter or operation in the order stated; then apply one rule consistently instead of guessing from the final pair alone. In a letter series, translate letters into positions A=1 through Z=26 and preserve wraparound. In a number series, record differences, ratios or alternating operations.
