Select the triad that follows the same pattern as: AD-BE-CF and GJ-HK-IL.
PS-QT-RU
PS-QU-RT
PQ-RS-TU
PS-QT-RV
PS-QT-RU
Observe the first letters of the clusters: A (1) тЖТ B (2) тЖТ C (3) and G (7) тЖТ H (8) тЖТ I (9). Follow the +1 increment across consecutive clusters for all positions.
Observe the first letters of the clusters: A (1) тЖТ B (2) тЖТ C (3) and G (7) тЖТ H (8) тЖТ I (9). Follow the +1 increment across consecutive clusters for all positions.
Analyze the first pattern (AD-BE-CF)
Looking at the first letters: A(1), B(2), C(3). Looking at the second letters: D(4), E(5), F(6). Each cluster advances by 1 position forward in the alphabet.
Analyze the second pattern (GJ-HK-IL)
Looking at the first letters: G(7), H(8), I(9). Looking at the second letters: J(10), K(11), L(12). The gap between letters within each cluster (e.g., A to D is +3) remains constant.
Verify Option A
In PS-QT-RU: P(16), Q(17), R(18) for first letters. S(19), T(20), U(21) for second letters. The internal gap (P to S is +3) matches the pattern AD (+3), BE (+3), CF (+3) and GJ (+3), HK (+3), IL (+3).
B: The internal gap between Q and U is +4, violating the +3 rule. C: The letters do not maintain the consecutive progression sequence required by the triad pattern. D: The third cluster RV has an internal gap of +4 instead of +3.
A is correct because it follows the triple-pair sequence where the first letters are consecutive (P, Q, R) and second letters are consecutive (S, T, U) while maintaining a fixed internal gap of +3 between cluster letters.
When analyzing triads, check the 'delta' or gap between the first and second letter of every single pair; if it is constant (like +3 here), the answer must replicate that exact gap.
