Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
LAS, NFW, MKD, OPH, LUS, ?
Answer & explanation
Correct answer: option 3
Explanation:
LAS, NFW, MKD, OPH, LUS, ?
The logic followed here is :
L → (+2) → N → (-1) → M → (+2) → O → (-3) → L → (+2) → N
A → (+5) → F → (+5) → K → (+5) → P → (+5) → U → (+5) → Z
S → (+4) → W → (+7) → D → (+4) → H → (+11) → S → (+4) → W
So, the letter-cluster that replaces the (?) to complete the series is "NZW"
