Which letter-cluster will replace the question mark (?) and complete the given series?
MCRV, PFQU, ?, VLOS, YONR
- ASIQP
- BSHPR
- CSIPT
- DSIQT
Solution & Step-by-step Explanation
Let's track the position changes for each letter in the clusters step-by-step:
1st letter: M (13) → P (16) → S (19) → V (22) → Y (25) (Pattern: +3)
2nd letter: C (3) → F (6) → I (9) → L (12) → O (15) (Pattern: +3)
3rd letter: R (18) → Q (17) → P (16) → O (15) → N (14) (Pattern: −1)
4th letter: V (22) → U (21) → T (20) → S (19) → R (18) (Pattern: −1)
Combining these, the missing letter-cluster is SIPT.
