Which of the given letter-clusters will replace the question mark (?) in the following series?
UDPJ, YHTN, CLXR, ?, KTFZ
- AGPBV
- BGPCU
- CGPBU
- DGPBW
Solution & Step-by-step Explanation
Let's find the shift pattern for each corresponding letter in the clusters:
1st Letter: U (+4) → Y (+4) → C (+4) → G (+4) → K
2nd Letter: D (+4) → H (+4) → L (+4) → P (+4) → T
3rd Letter: P (+4) → T (+4) → X (+4) → B (+4) → F (Note: X(24) + 4 = 28 → B)
4th Letter: J (+4) → N (+4) → R (+4) → V (+4) → Z
Combining these letters gives GPBV.
