Select the letter-pair that can replace the question mark (?) in the following series.
JL, GJ, DH, AF, ?
Answer & explanation
Correct answer: option 4
Explanation:
JL, GJ, DH, AF, ?
The logic followed here is :
J → (-3) → G → (-3) → D → (-3) → A → (-3) → X
L → (-2) → J → (-2) → H → (-2) → F → (-1) → D
So, the letter-cluster that replaces the (?) to complete the series is "XD"
