Which letter-cluster will replace the question mark (?) to complete the given series?
ZVFM, XRJO, ?, TJRS, RFVU
- AVMOQ
- BVMOR
- CVNMR
- DVNNQ
Solution & Step-by-step Explanation
Let's check the pattern for each corresponding letter in the clusters:
1st Letter: Z (-2) → X (-2) → V (-2) → T (-2) → R
2nd Letter: V (-4) → R (-4) → N (-4) → J (-4) → F
3rd Letter: F (+4) → J (+4) → N (+4) → R (+4) → V
4th Letter: M (+2) → O (+2) → Q (+2) → S (+2) → U
Combining these results, the missing cluster is VNNQ.
