To determine the 5th term of the sequence where the $n$-th term rule is given as $3^n$, let’s calculate step by step:

1. The $n$-th term is expressed as $3^n$.

2. For the 5th term ($n = 5$): $3^5 = 3 \times 3 \times 3 \times 3 \times 3$

3. Simplifying: $3^5 = 243$

Final Answer:

The 5th term of the sequence is 243.
