VLE
ULE
WLD

WLD
Observe the first and second letters increase by +2 while the third letter increases by +2, with alphabet wrapping (Z to A).
Observe the first and second letters increase by +2 while the third letter increases by +2, with alphabet wrapping (Z to A).
Analyze the first letters
The first letters are M(13), O(15), Q(17), S(19), U(21). The pattern is +2. Therefore, the next letter is 21 + 2 = 23, which is W.
Analyze the second letters
The second letters are B(2), D(4), F(6), H(8), J(10). The pattern is +2. Therefore, the next letter is 10 + 2 = 12, which is L.
Analyze the third letters
The third letters are T(20), V(22), X(24), Z(26), B(2). The pattern is +2 (wrapping around Z). Therefore, the next letter is 2 + 2 = 4, which is D.
A: VLE is incorrect because the first letter must be W, not V. B: ULE is incorrect because the first letter must be W, not U. D: ULD is incorrect because the first letter must be W, not U.
C is correct because the series follows a consistent +2/+2/+2 pattern for each letter position, resulting in WLD.
In alphabetical series, always convert letters to their numerical positions (A=1, Z=26) to spot arithmetic jumps quickly.
