Identify Series Structure

The given series is Y25M13Q17D4?12. Observe that the series consists of alternating letters and numbers, forming pairs.

The pairs are:

  • Pair 1: Y and 25
  • Pair 2: M and 13
  • Pair 3: Q and 17
  • Pair 4: D and 4
  • Pair 5: ? and 12

Determine Letter-Number Pattern

Analyze the relationship between the letter and the number within each pair:

  • Y is the 25th letter of the alphabet, and the number is 25.
  • M is the 13th letter of the alphabet, and the number is 13.
  • Q is the 17th letter of the alphabet, and the number is 17.
  • D is the 4th letter of the alphabet, and the number is 4.

The pattern is that the number in each pair corresponds to the alphabetical position of the letter.

Find the Missing Letter

Applying this pattern to the last pair:

  • The number is 12.
  • Therefore, the missing letter must be the 12th letter of the alphabet.

The 12th letter of the alphabet is L.

Thus, the missing element in the series is L.
