In the following question, a series is given with one term missing. Choose the correct term to complete the sequence.
AZ, CX, EV, GT, ?
Show answer & explanation
Correct answer: C
Explanation
The given letter series follows this pattern:
• First letter: Increases by 2 positions in alphabetical order:
A (+2) → C (+2) → E (+2) → G (+2) → I
• Second letter: Decreases by 2 positions in alphabetical order (or each pair consists of opposite letters):
Z (−2) → X (−2) → V (−2) → T (−2) → R
Therefore, the missing term is IR.
