Observe the first, second, and third letters of each cluster independently; they follow constant addition patterns (+3, +5, +3 respectively).
Observe the first, second, and third letters of each cluster independently; they follow constant addition patterns (+3, +5, +3 respectively).
Analyze the first letter of each cluster
The first letters are I(9), L(12), O(15), R(18). The pattern is +3: 9+3=12(L), 12+3=15(O), 15+3=18(R), 18+3=21(U).
Analyze the second letter of each cluster
The second letters are N(14), Q(17), T(20), W(23). The pattern is +3: 14+3=17(Q), 17+3=20(T), 20+3=23(W), 23+3=26(Z).
Analyze the third letter of each cluster
The third letters are J(10), M(13), P(16), S(19). The pattern is +3: 10+3=13(M), 13+3=16(P), 16+3=19(S), 19+3=22(V).
A: VUZ is incorrect because it misses the established +3 increment for the first, second, and third positions. B: UVZ is incorrect because the second and third letters are swapped from the required logic. D: VZU is incorrect because it deviates from the constant +3 sequence for every positional index.
C is correct because the sequence follows a strict +3 increment for all three positions simultaneously, resulting in U(21), Z(26), and V(22).
For multi-letter series, always solve the pattern for each column individually rather than viewing the cluster as a whole word, as this prevents common mistakes in sequence tracking.
