Observe the first, second, and third letters of the triplets separately as three independent series, each decreasing by 1 in the alphabet.
Observe the first, second, and third letters of the triplets separately as three independent series, each decreasing by 1 in the alphabet.
Analyze the first letter of each triplet
J (10), I (9), H (8), G (7). The pattern is -1. Next is 7 - 1 = 6, which corresponds to F.
Analyze the second letter of each triplet
M (13), L (12), K (11), J (10). The pattern is -1. Next is 10 - 1 = 9, which corresponds to I.
Analyze the third letter of each triplet
Q (17), P (16), O (15), N (14). The pattern is -1. Next is 14 - 1 = 13, which corresponds to M.
A: FJM is incorrect because the third letter should be M, not J. B: FIN is incorrect because the third letter should be M, not N. D: FJN is incorrect because the second letter should be I and the third letter should be M.
C is correct because applying a -1 decrease to each letter position in the sequence GJN results in FIM.
When dealing with multi-letter series, always break them into individual positional series to avoid confusion; this turns one complex problem into three simple arithmetic ones.
