Calculate the difference between the starting letter of the first term and the starting letter of the second term, then apply that jump (+9) to the starting letter of the third term.
Calculate the difference between the starting letter of the first term and the starting letter of the second term, then apply that jump (+9) to the starting letter of the third term.
Analyze the relationship between BDF and KMO
Map letters to positions: B(2), D(4), F(6) and K(11), M(13), O(15). The transformation is B to K (+9), D to M (+9), F to O (+9).
Apply the same logic to HJL
Start with H(8), J(10), L(12). Adding 9 to each position: 8+9=17(Q), 10+9=19(S), 12+9=21(U). The resulting cluster is QSU.
B: RTV is incorrect because R(18) is +10 from H(8), C: PSU is incorrect because P(16) is +8 from H(8), D: NPR is incorrect because N(14) is +6 from H(8).
A is correct because every letter in the first cluster (B, D, F) is shifted forward by 9 positions to arrive at the corresponding letter in the second cluster (K, M, O), and applying the same +9 shift to HJL results in QSU.
For letter analogies, always write down the numerical position of letters (A=1, B=2...) to identify patterns instantly instead of counting on your fingers.
