Select the pair which follows the same coding pattern as the given pair: YQ тИТ CU
AS тИТ EW
DV тИТ HZ
UM тИТ ZN
All of the above

Convert each letter to its alphabetical position. Check the difference between the first and second letters, and the third and fourth letters in each pair.
Convert each letter to its alphabetical position. Check the difference between the first and second letters, and the third and fourth letters in each pair.
Analyze Pair A (YQ - CU)
Y = 25, Q = 17 (Difference: 17 - 25 = -8). C = 3, U = 21 (Difference: 21 - 3 = +18).
Analyze Pair B (AS - EW)
A = 1, S = 19 (Difference: 19 - 1 = +18). E = 5, W = 23 (Difference: 23 - 5 = +18).
Analyze Pair C (DV - HZ)
D = 4, V = 22 (Difference: 22 - 4 = +18). H = 8, Z = 26 (Difference: 26 - 8 = +18).
Analyze Pair D (UM - ZN)
U = 21, M = 13 (Difference: 13 - 21 = -8). Z = 26, N = 14 (Difference: 14 - 26 = -12). Both parts show negative differences (-8 and -12), making it the odd one out.
A: Has +18 in the second cluster. B: Both clusters follow a +18 forward alphabetical shift. C: Both clusters follow a +18 forward alphabetical shift. D: Correctly identified as odd one out due to negative shifts in both parts.
D is correct because UM - ZN does not follow the uniform positive +18 positional shift observed in the other pairs.
Always test both forward and backward numerical positional differences when letter cluster patterns are not immediately obvious.
