**Candy Machine Problem**

Think back to the magical candy machine at your neighborhood grocery store. Suppose that the first time a quarter is put into the machine, 1 Skittle comes out. The second time, 5 Skittles, the third time 25 Skittles, the fourth time, 125 Skittles, etc.

a. Find both a recursive and closed formula for how many Skittles the nth customer gets.

- **Recursive formula:** \( a_n = \) 
- **Closed formula:** \( a_n = \) 

b. Check your solution for the closed formula by solving the recurrence relation using the Characteristic Root technique.
