Observe the first, second, and third letters of each triplet independently. Each letter follows a +3 alphabetical progression sequence.
Analyze 1st Letters
The first letters are E(5), H(8), K(11), N(14). Following the +3 pattern, N(14) + 3 = 17, which is Q.
Analyze 2nd Letters
The second letters are G(7), J(10), M(13), P(16). Following the +3 pattern, P(16) + 3 = 19, which is S.
Analyze 3rd Letters
The third letters are K(11), N(14), Q(17), T(20). Following the +3 pattern, T(20) + 3 = 23, which is W.
A: Incorrect as it does not follow the +3 pattern. B: Incorrect sequence of letters. D: Incorrect, letters are out of the established +3 logic order.
C is correct because the series follows a consistent +3 pattern for each position: E+3=H, G+3=J, K+3=N, resulting in the triplet QSW.
For triplet series, always decompose the problem into three separate parallel series. It prevents mixing up the logic and significantly increases speed.
