Find the middle term in the expansion of `(x^2+1/(x^2)+2)^ndot`

Explanation

To find the middle term in the expansion of \((x^2 + \frac{1}{x^2} + 2)^n\), we can follow these steps:

### Step 1: Rewrite the Expression
We start with the expression:
\[ (x^2 + \frac{1}{x^2} + 2)^n \]
Notice that \(x^2 + \frac{1}{x^2} + 2\) can be rewritten. We can express \(x^2 + \frac{1}{x^2}\) as \((x + \frac{1}{x})^2 - 2\):
