Which letter cluster will replace the question mark (?) to complete the given series?
NAME, NEME, ?, NOME, NUME
Answer & explanation
Correct answer: option 3

Explanation:
NAME, NEME, ?, NOME, NUME
The logic followed here is :
N → (0) → N → (0) → N → (+7) → N → (+7) → N
A → (-9) → E → (-9) → I → (-9) → O → (-9) → U
M → (+8) → M → (+8) → M → (+8) → M → (+8) → M
E → (-10) → E → (-10) → E → (-10) → E → (-10) → E
So, the letter-cluster that replaces the (?) to complete the series is "NIME"
