Look at the first, second, and third letters separately. Each column follows a simple +1 alphabetical progression: L-M-N-O → P; N-O-P-Q → R; I-J-K-L → M.
Analyze the 1st letters
The first letters are L, M, N, O. Following the pattern (L=12, M=13, N=14, O=15), the next letter is 16, which is P.
Analyze the 2nd letters
The second letters are N, O, P, Q. Following the pattern (N=14, O=15, P=16, Q=17), the next letter is 18, which is R.
Analyze the 3rd letters
The third letters are I, J, K, L. Following the pattern (I=9, J=10, K=11, L=12), the next letter is 13, which is M.
A: RMP starts with R instead of P. B: RPM has incorrect 2nd and 3rd letters. C: PMR has incorrect 2nd and 3rd letters.
D is correct because the series follows a consistent +1 progression for each letter position, resulting in the sequence P, R, M.
Always break down multi-letter series into individual positions; usually, each position evolves independently according to a simple constant increment or pattern.
