SSC CGL (Prelims) General: Series Completion questions with solutions

Q1. Select the letter cluster from among the given options that can replace the question mark (?) in the following series: XZYX, XYXX, XXWX, XWVX, ?

1. XVUX
2. XTVX
3. XUVX
4. XUTX

Answer: XVUX

The series keeps X at the first and last positions, while the middle letters shift in a systematic way. Continuing the pattern leads to XVUX, which fits the sequence.
