Based on the English alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
FHD
VST
ZWX
NKL
FHD
Check the alphabetical position differences between consecutive letters in each letter-cluster. One cluster will follow a different arithmetic pattern from the other three.
Check the alphabetical position differences between consecutive letters in each letter-cluster. One cluster will follow a different arithmetic pattern from the other three.
Analyze Option A (FHD)
F is 6, H is 8 (difference is +2). H is 8, D is 4 (difference is -4). The pattern is +2, -4.
Analyze Option B (VST)
V is 22, S is 19 (difference is -3). S is 19, T is 20 (difference is +1). The pattern is -3, +1.
Analyze Option C (ZWX)
Z is 26, W is 23 (difference is -3). W is 23, X is 24 (difference is +1). The pattern is -3, +1.
Analyze Option D (NKL)
N is 14, K is 11 (difference is -3). K is 11, L is 12 (difference is +1). The pattern is -3, +1.
B: Follows the standard -3, +1 alphabetical gap rule. C: Follows the standard -3, +1 alphabetical gap rule. D: Follows the standard -3, +1 alphabetical gap rule.
A is correct because FHD follows a +2, -4 pattern between consecutive letters, whereas VST, ZWX, and NKL all follow a -3, +1 pattern.
In alphabetical reasoning questions, always write down the numeric positions (1 to 26) of the letters first to quickly uncover arithmetic differences.
