**1. Homework Statement**

Find the limit for the following sequence and then use the definition of limit to justify your result.

**2. Homework Equations**

n^3/(2*n^3 + n)

**3. The Attempt at a Solution**

I found the limit as n --> infinity is 1/2. I think the next step is to set up the equation as follows:

n^3/(2*n^3 + n) = 1/2

But then I'm not sure if I should add n+1 to each side.
