Analyze each position (1st, 2nd, 3rd letters) separately. The 1st letter increases by +4, the 2nd by +4, and the 3rd by +2 in each term.
Analyze 1st Letters
G(7), K(11), O(15), S(19). The pattern is +4. Next: S(19) + 4 = 23 (W).
Analyze 2nd Letters
F(6), J(10), N(14), R(18). The pattern is +4. Next: R(18) + 4 = 22 (V).
Analyze 3rd Letters
C(3), E(5), G(7), I(9). The pattern is +2. Next: I(9) + 2 = 11 (K).
A: WXM is incorrect because the 2nd and 3rd letters do not follow the sequence. B: WXL is incorrect because the 3rd letter does not follow the +2 sequence. D: XYK is incorrect because the 1st and 2nd letters do not follow the +4 sequence.
C is correct because the series follows a specific increment for each position: (1st: +4), (2nd: +4), (3rd: +2), resulting in WVK.
For alphabetical series, always break the term into individual letters and write their numeric positions to quickly spot additive or subtractive patterns.
