Which letter will replace the question mark (?) in the following letter series?
E, J, N, Q, S, ?
Answer & explanation
Correct answer: option 1

Explanation:
E, J, N, Q, S, ?
The logic followed here is :
E → (+5) → J → (+4) → N → (+3) → Q → (+2) → S → (+1) → T
So, the letter-cluster that replaces the (?) to complete the series is "T"
