In the following question, various terms of an alphabet series are given with one or more missing terms as shown by (?).
Choose the missing term out of the given alternatives.
A, C, E, G, I, ?
- A.
K
- B.
L
- C.
M
- D.
N
Show answer & explanation
Correct answer: A
Concept: In an alphabet series where consecutive terms have a constant letter-position gap, each term's position value (A=1 ... Z=26) equals the previous term's position value plus that fixed gap. Find the gap from the given terms, then apply it to the last given term to get the missing one.
Application:
Assign position values to the given letters: A=1, C=3, E=5, G=7, I=9.
Find the gap between each pair of consecutive terms: 3-1=2, 5-3=2, 7-5=2, 9-7=2 — a constant gap of +2.
Apply the same +2 gap to the last given term, I (position 9): 9+2=11.
Convert position 11 back to a letter: the 11th letter of the alphabet is K.
Cross-check: Writing out the series while skipping exactly one letter each time — A, C, E, G, I, K — confirms the +2 gap holds consistently across every pair, independently verifying the same result.
Therefore, the missing term is K.
