Analyze each position in the triplets independently. The first letter decreases by 1, the second letter decreases by 3, and the third letter decreases by 1.
Analyze each position in the triplets independently. The first letter decreases by 1, the second letter decreases by 3, and the third letter decreases by 1.
Analyze 1st Letters
The first letters are T (20), S (19), R (18), Q (17). The pattern is -1 for each step. The next letter is 17 - 1 = 16, which is P.
Analyze 2nd Letters
The second letters are W (23), V (22), U (21), T (20). The pattern is -1 for each step. The next letter is 20 - 1 = 19, which is S.
Analyze 3rd Letters
The third letters are P (16), O (15), N (14), M (13). The pattern is -1 for each step. The next letter is 13 - 1 = 12, which is L.
A: PLS is incorrect as the order of letters in the triplet is reversed. C: LSP is incorrect as it shuffles the sequence. D: LPS is incorrect as it misplaces the position of the letters.
B is correct because the series follows a consistent pattern where each letter in the triplet shifts backward by 1 position (T-S-R-Q тЖТ P, W-V-U-T тЖТ S, P-O-N-M тЖТ L), resulting in PSL.
In alphabetical series, always convert letters to their numerical positions (A=1, B=2...) to quickly identify simple arithmetic sequences.
