The given expression is:

\[
\frac{6^{2n+1} \times 3^{n-2}}{18^{n+2}}
\]

Let's simplify this step by step.

### Step 1: Express \( 18 \) as a product of primes
Since \( 18 = 2 \times 3^2 \), we can rewrite the denominator:

\[
18^{n+2} = (2 \times 3^2)^{n+2} = 2^{n+2} \times 3^{2(n+2)}
\]

Thus, the expression becomes:

\[
\frac{6^{2n+1} \times 3^{n-2}}{2^{n+2} \times 3^{2(n+2)}}
\]

### Step 2: Express \( 6 \) as a product of primes
Since \( 6 = 2 \times 3 \), we can rewrite \( 6^{2n+1} \):

\[
6^{2n+1} = (2 \times 3)^{2n+1} = 2^{2n+1} \times 3^{2n+1}
\]

Now the expression becomes:

\[
\frac{2^{2n+1} \times 3^{2n+1} \times 3^{n-2}}{2^{n+2} \times 3^{2n+4}}
\]

### Step 3: Combine powers of 2 and 3
Let's combine the powers of 2:

\[
\frac{2^{2n+1}}{2^{n+2}} = 2^{(2n+1) - (n+2)} = 2^{n-1}
\]

Now for the powers of 3:

\[
\frac{3^{2n+1} \times 3^{n-2}}{3^{2n+4}} = 3^{(2n+1 + n - 2) - (2n+4)} = 3^{n-5}
\]

### Step 4: Final simplified expression
The simplified expression is:

\[
2^{n-1} \times 3^{n-5}
\]

This is the final simplified result.
