Track position changes independently for the 1st, 2nd, and 3rd letters of each term by analyzing their alphabetical shift values.
Track position changes independently for the 1st, 2nd, and 3rd letters of each term by analyzing their alphabetical shift values.
Analyze 1st Letters
B (2) + 4 = F (6), F (6) + 4 = J (10), J (10) + 4 = N (14), N (14) + 4 = R (18). Continuing the pattern, R (18) + 4 = 22, which corresponds to V.
Analyze 2nd Letters
E (5) + 4 = I (9), I (9) + 4 = M (13), M (13) + 4 = Q (17), Q (17) + 4 = U (21). Continuing the pattern, U (21) + 4 = 25, which corresponds to Y.
Analyze 3rd Letters
V (22) - 4 = R (18), R (18) - 4 = N (14), N (14) - 4 = J (10), J (10) - 4 = F (6). Continuing the pattern, F (6) - 4 = 2, which corresponds to B.
Combine the Letters
Combining the next letters in order gives V Y B.
A: TUS is incorrect as it does not follow the correct letter position shifts. C: YVB has letters in the incorrect position order. D: STU is incorrect.
B is correct because the sequence follows a strict pattern where the first and second letters increase by +4 positions each step, while the third letter decreases by -4 positions, yielding V Y B.
When analyzing multi-letter series, always break down the terms and test independent shifts for each position (1st, 2nd, 3rd) rather than looking at the term as a single block.
