Which letter cluster will replace the question mark (?) to complete the given series?
abCD, fgHI, ?, stUV, abCD
Answer & explanation
Correct answer: option 2
Explanation:
abCD, fgHI, ?, stUV, abCD
The logic followed here is :
a → (+5) → f → (+6) → l → (+7) → s→ (+8) → s
b → (+5) → g → (+6) → m → (+7) → t → (+8) → b
C → (+5) → H → (+6) → N → (+7) → U → (+8) → C
D → (+5) → I → (+6) → O → (+7) → V → (+8) → D
So, the letter-cluster that replaces the (?) to complete the series is "lmNO"
