Observe the first, second, and third letters of each triplet independently; each letter in the sequence follows a consistent -2 pattern relative to its counterpart in the previous triplet.
Analyze First Letter Pattern
The first letters are U(21), S(19), Q(17), O(15), M(13). Each step is -2. Therefore, 13 - 2 = 11, which is K.
Analyze Second Letter Pattern
The second letters are T(20), R(18), P(16), N(14), L(12). Each step is -2. Therefore, 12 - 2 = 10, which is J.
Analyze Third Letter Pattern
The third letters are W(23), U(21), S(19), Q(17), O(15). Each step is -2. Therefore, 15 - 2 = 13, which is M.
A: LJM is incorrect as the first letter must be K and the second J; B: KJN is incorrect as the third letter must be M; D: LKN is incorrect as both the first and third letters do not match the -2 sequence.
C is correct because the series follows a consistent -2 decrement pattern for all three positions (K, J, M).
For alphabetical series, always convert letters to their numerical positions (A=1, Z=26) to spot arithmetic progressions quickly.
