Answer:

geometric

Step-by-step explanation:

The signs of the terms alternate, so it cannot be an arithmetic sequence.

The ratios of terms are ...

6/-3 = -12/6 = 24/-12 = -2

The terms have a constant ratio of -2, so the sequence is geometric.

Exponential Rule [Multiplying]: $\displaystyle b^m \cdot b^n = b^{m + n}$
Exponential Rule [Dividing]: $\displaystyle \frac{b^m}{b^n} = b^{m - n}$

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{3^3 \cdot 3^3}{3^4}$

Step 2: Simplify

[ER] Multiply: $\displaystyle \frac{3^{3+3}}{3^4}$
Add Exponents: $\displaystyle \frac{3^6}{3^4}$
[ER] Divide: $\displaystyle 3^{6 - 4}$
Subtract Exponents: $\displaystyle 3^2$
