ZVU
ZYV

Look at the positional difference for each corresponding letter across consecutive 3-letter terms. Every letter in each term increases by +5 positions in the English alphabet.

Analyze 1st Letters
F (6) + 5 = K (11), K (11) + 5 = P (16), P (16) + 5 = U (21). Continuing the pattern: U (21) + 5 = Z (26).
Analyze 2nd Letters
E (5) + 5 = J (10), J (10) + 5 = O (15), O (15) + 5 = T (20). Continuing the pattern: T (20) + 5 = Y (25).
Analyze 3rd Letters
B (2) + 5 = G (7), G (7) + 5 = L (12), L (12) + 5 = Q (17). Continuing the pattern: Q (17) + 5 = V (22).
A: ZXS is incorrect because the third letter should be V, not S. B: ZVU is incorrect because the second and third letters do not follow the +5 sequence. D: YZU is incorrect because the starting letter should be Z.
C is correct because applying a +5 positional shift to each letter of the term UTQ yields Z, Y, and V respectively, giving ZYV.
For multi-letter series questions, always analyze each position independently (1st with 1st, 2nd with 2nd, etc.) rather than treating the group as a single word.
