Solve the following math problem efficiently and clearly:

- For simple problems (2 steps or fewer):
Provide a concise solution with minimal explanation.

- For complex problems (3 steps or more):
Use this step-by-step format:

## Step 1: [Concise description]
[Brief explanation and calculations]

## Step 2: [Concise description]
[Brief explanation and calculations]

...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: Suppose $\sin N = \frac{2}{3}$ in the diagram below.  What is $LN$?

pair L,M,N;
M = (0,0);
N = (17.89,0);
L = (0,16);
draw(L--M--N--L);
draw(rightanglemark(L,M,N,18));
label("$M$",M,SW);
label("$N$",N,SE);
label("$L$",L,NE);
label("$16$",L/2,W);
