Calculate the shifts for each of the three letters independently by comparing the alphabetical positions (F=6, C=3, Z=26, W=23) and observing the constant gap of -3 across the sequence.
Calculate the shifts for each of the three letters independently by comparing the alphabetical positions (F=6, C=3, Z=26, W=23) and observing the constant gap of -3 across the sequence.
Analyze the first letter of each cluster
F(6) to C(3) is -3. C(3) to Z(26) is -3 (3-3=0, which is Z). Z(26) to W(23) is -3. Following this pattern, W(23) - 3 = 20, which is T.
Analyze the second letter of each cluster
X(24) to U(21) is -3. U(21) to R(18) is -3. R(18) to O(15) is -3. Following this pattern, O(15) - 3 = 12, which is L.
Analyze the third letter of each cluster
I(9) to F(6) is -3. F(6) to C(3) is -3. C(3) to Z(26) is -3 (3-3=0, which is Z). Following this pattern, Z(26) - 3 = 23, which is W.
A: RMU starts with R and has U at end, incorrect; B: SNV starts with S, incorrect; C: SOU starts with S, incorrect.
D is correct because each letter in the cluster follows a -3 shift pattern, resulting in T, L, and W respectively.
When dealing with letters that wrap around Z to A, always convert letters to their numerical positions (A=1, Z=26) and treat the sequence as circular math (mod 26).
