Analyze 1st Letters
J (10), K (11), L (12), M (13). Each letter increases by +1. The next letter is N (14).
Analyze 2nd Letters
F (6), G (7), H (8), I (9). Each letter increases by +1. The next letter is J (10).
Analyze 3rd Letters
H (8), I (9), J (10), K (11). Each letter increases by +1. The next letter is L (12).
Form Final Term
Combining the next letters gives N, J, and L, which forms JNL.
B: NJL has incorrect letter order. C: JLN has incorrect starting sequence. D: NLJ reverses the progression entirely.
A is correct because each letter in the triplet advances by +1 alphabetically relative to the previous term, yielding JNL.
Always check positional increments independently for each letter position in multi-letter series questions.
