To define a recursive formula for the number of jewels that Jose can collect at level \( n \), we start by establishing the relationship between levels.
1. At level 1, the number of jewels is given as \( 5 \).
2. The number of jewels doubles at each subsequent level. Therefore:
- At level 2, the number of jewels is \( 2 \times 5 = 10 \).
- At level 3, the number of jewels is \( 2 \times 10 = 20 \).
- At level 4, the number of jewels is \( 2 \times 20 = 40 \).
- And so on.
From this, we can derive the recursive formula:
- Base case: \( J(1) = 5 \)
- Recursive case: \( J(n) = 2 \times J(n-1) \) for \( n > 1 \)
Thus, the full recursive formula is:
\[
J(n) =
\begin{cases}
5 & \text{if } n = 1 \\
2 \cdot J(n-1) & \text{if } n > 1
\end{cases}
\]
This formula describes how the number of jewels collected grows with each level.
