Select the term from among the given options that can replace the question mark (?) in the following series. D4W, G5T, K9P, ?, S23H, V37E

The letters seem to be progressing alphabetically, and the numbers seem to be increasing by a certain pattern. Let's observe the pattern: From D4W to G5T, the letter increases by 3 (D -> G) and the number increases by 1 (4 -> 5). From G5T to K9P, the letter increases by 4 (G -> K) and the number increases by 4 (5 -> 9). So, it seems like the pattern is that the letter increases by a certain value (3, 4, ...) and the number increases by the same value (1, 4, ...). If we follow this pattern: From K9P to the next term, the letter should increase by 5 (K -> O) and the number should increase by 5 (9 -> 14). So, the next term should start with O14. Among the options, only option 4 has O14L, so the correct answer is: O14L
