MNB
JMC
GLC
KKD
KKD
Observe the first, second, and third letters of each cluster independently, identifying the increment sequence for each position (1st letter: +1, 2nd letter: +2, 3rd letter: +3).
Observe the first, second, and third letters of each cluster independently, identifying the increment sequence for each position (1st letter: +1, 2nd letter: +2, 3rd letter: +3).
Analyze the first letter of each cluster
G (7) → H (8) → I (9) → J (10) → K (11). The pattern is +1 for each step. The next letter is K.
Analyze the second letter of each cluster
C (3) → E (5) → G (7) → I (9) → K (11). The pattern is +2 for each step. The next letter is K.
Analyze the third letter of each cluster
R (18) → U (21) → X (24) → A (27/1) → D (4). The pattern is +3 for each step. The next letter is D.
A: MNB does not follow the +1, +2, +3 progression. B: JMC fails the pattern at all three positions. C: GLC fails the first and second letter progression.
D is correct because the series follows a consistent +1, +2, +3 increment pattern for the first, second, and third positions respectively, resulting in KKD.
For alphabetical series, always convert letters to their numeric positions (A=1, Z=26) immediately to identify arithmetic gaps faster.
