The correct answer is
M13N

Solving the Alphanumeric Series G7H, I9J, K11L

We need to identify the pattern in the series G7H, I9J, K11L and find the next term.

Analyzing the Series Pattern

The series consists of three parts: a starting letter, a number, and an ending letter.

  • First Letter: The sequence is G, I, K. These letters are spaced two positions apart in the alphabet (G, skip H, I; I, skip J, K). The next letter follows this pattern: K, skip L, M.
  • Number: The sequence is 7, 9, 11. This is an arithmetic sequence where 2 is added to each term ($7, 7+2=9, 9+2=11$). The next term is $11 + 2 = 13$.
  • Second Letter: The sequence is H, J, L. These letters are also spaced two positions apart in the alphabet (H, skip I, J; J, skip K, L). The next letter follows this pattern: L, skip M, N.

Determining the Next Term

Combining the identified patterns:

  • The next first letter is M.
  • The next number is 13.
  • The next second letter is N.

Therefore, the complete next term in the series is M13N.

This corresponds to Option C.
