Which of the following letter-clusters will replace the question mark (?) in the given series?
ARC, EPF, JNI, PLL, ?
Answer & explanation
Correct answer: option 1
Explanation:
ARC, EPF, JNI, PLL, ?
The logic followed here is :
A → (+4) → E → (+5) → J → (+6) → P → (+7) → W
R → (-2) → P → (-2) → N → (-2) → L → (-2) → J
C → (+3) → F → (+3) → I → (+3) → L → (+3) → O
So, the letter-cluster that replaces the (?) to complete the series is "WJO"
