**Arithmetic and Geometric Sequences Challenge**

1. **Arithmetic Sequence Problem:**
   - Find \( x \) and \( y \) such that the sequence \( 5, x, y, 38 \) is part of an arithmetic sequence.
   - Solution boxes:
     - \( x = \_\_\_\_\_ \)
     - \( y = \_\_\_\_\_

2. **Geometric Sequence Problem:**
   - Then find \( x \) and \( y \) so that the sequence is part of a geometric sequence.
   - Solution boxes:
     - \( x = \_\_\_\_\_ \)
     - \( y = \_\_\_\_\_

*Note: \( x \) and \( y \) might not be integers.*
