The correct answer is
U

This question requires identifying the pattern in the given alphabet series and finding the next term.

Alphabet Series Pattern Analysis

The series is: A, C, F, J, O, ?

Let's examine the gaps (number of letters skipped) between consecutive terms:

  • A to C: Skip 1 letter (B).
  • C to F: Skip 2 letters (D, E).
  • F to J: Skip 3 letters (G, H, I).
  • J to O: Skip 4 letters (K, L, M, N).

Identifying the Progression

The number of skipped letters follows a clear pattern of increasing by 1 each time: 1, 2, 3, 4.

Finding the Next Term

Following the established pattern, the next step requires skipping 5 letters after O.

The letters after O are P, Q, R, S, T. Skipping these 5 letters brings us to the next letter in the series.

Therefore, the next letter is U.
