Select the letter from among the given options that can replace the question mark (?) in the following series. H, Q, I, T, K, ?, N

Y A U J

Y

Explanation: H, Q, I, T, K, ?, N The logic followed here is : H → (+1) → I, I → (+2) → K, K → (+3) → N Q → (+3) → T, T → (+5) → Y   So, the letter-cluster that replaces the (?) to complete the series is "Y"
