Which of the following letter cluster will replace the question mark (?) to complete the given series?
PTX, AEI, LPT, ?
Answer & explanation
Correct answer: option 4
Explanation:
PTX, AEI, LPT, ?
The logic followed here is :
P → (+11) → A → (+11) → L → (+11) → W
T → (+11) → E → (+11) → P → (+11) → A
X → (+11) → I → (+11) → T → (+11) → E
So, the letter-cluster that replaces the (?) to complete the series is "WAE"
