Which letter-cluster will replace the question mark (?) to complete the given series?
KRPD, ?, QNRL, TLSP, WJTT
Answer & explanation
Correct answer: option 4
Explanation:
KRPD, ?, QNRL, TLSP, WJTT
The logic followed here is :
K → (+3) → N → (+3) → Q → (+3) → T → (+3) → W
R → (-2) → P → (-2) → N → (-2) → L → (-2) → J
P → (+1) → Q → (+1) → R → (+1) → S → (+1) → T
D → (+4) → H → (+4) → L → (+4) → P → (+4) → T
So, the letter-cluster that replaces the (?) to complete the series is "NPQH"
