Which letter-cluster will replace the question mark (?) to complete the given series?
XSMP, WTKR, VUIT, ?, TWEX
- AUVHW
- BUVGV
- CUWHV
- DUWFX
Solution & Step-by-step Explanation
Let's break down the series by analyzing the corresponding positional values of letters in each cluster:
1st letter: X (24) → W (23) → V (22) → U (21) → T (20) [-1 step]
2nd letter: S (19) → T (20) → U (21) → V (22) → W (23) [+1 step]
3rd letter: M (13) → K (11) → I (9) → G (7) → E (5) [-2 steps]
4th letter: P (16) → R (18) → T (20) → V (22) → X (24) [+2 steps]
Combining the letters gives UVGV.
