Which of the following letter clusters will replace the question mark (?) and complete the following letter cluster series?
DW, FU, HS, JQ, LO, ?
Answer & explanation
Correct answer: option 3
Explanation:
DW, FU, HS, JQ, LO, ?
The logic followed here is :
D → (+2) → F → (+2) → H → (+2) → J → (+2) → L → (+2) → N → (+2)
W → (-2) → U → (-2) → S → (-2) → Q → (-2) → O → (-2) → M → (+2)
So, the letter-cluster that replaces the (?) to complete the series is "NM"
