Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
IDK, LFL, OHM, RJN, ?
Answer & explanation
Correct answer: option 2
Explanation:
IDK, LFL, OHM, RJN, ?
The logic followed here is :
I → (+3) → L → (+3) → O → (+3) → R → (+3) → U
D → (+2) → F → (+2) → H → (+2) → J → (+2) → L
K → (+1) → L → (+1) → M → (+1) → N → (+1) → O
So, the letter-cluster that replaces the (?) to complete the series is "ULO"
