Which of the following letter-cluster will replace the question mark(?) in the given series?
DBK, GDL, JFM, MHN, ?
Answer & explanation
Correct answer: option 3
Explanation:
DBK, GDL, JFM, MHN, ?
The logic followed here is :
D → (+3) → G → (+3) → J → (+3) → M → (+3) → P
B → (+2) → D → (+2) → F → (+2) → H → (+2) → J
K → (+1) → L → (+1) → M → (+1) → N → (+1) → O
So, the letter-cluster that replaces the (?) to complete the series is "PJO"
