What should come in place of the question mark (?) in the given series based on the English alphabetical order? DAG, FCI, HEK, JGM, ?
LIO
MJP
KGN
NLQ
LIO
Observe the first, middle, and last letters of each cluster independently; each follows a consistent +2 leap in the English alphabet sequence.
Observe the first, middle, and last letters of each cluster independently; each follows a consistent +2 leap in the English alphabet sequence.
Analyze the First Letter
D (4) → F (6) → H (8) → J (10) →?, Following +2, 10 + 2 = 12, which corresponds to L.
Analyze the Middle Letter
A (1) → C (3) → E (5) → G (7) →?, Following +2, 7 + 2 = 9, which corresponds to I.
Analyze the Last Letter
G (7) → I (9) → K (11) → M (13) →?, Following +2, 13 + 2 = 15, which corresponds to O.
B: MJP is incorrect because the sequence requires L, I, O based on the +2 pattern; C: KGN is incorrect as it does not follow the +2 increment for any position; D: NLQ is incorrect because it deviates from the identified +2 series logic.
A is correct because each letter in the cluster (DAG, FCI, HEK, JGM) advances by 2 positions in the alphabetical order (D+2=F, A+2=C, G+2=I), resulting in LIO for the final term.
For alphabetical series, always convert letters to their numerical positions (A=1, B=2, ... Z=26) first to quickly spot arithmetic patterns like +1, +2, or constant jumps.
