Find the sum to `n` terms of the sequence `(x+1//x)^2,(x^2+1//x)^2,(x^3+1//x)^2, ,`

Explanation

To find the sum of the first `n` terms of the sequence given by \((x + \frac{1}{x})^2, (x^2 + \frac{1}{x^2})^2, (x^3 + \frac{1}{x^3})^2, \ldots\), we can follow these steps:

### Step 1: Identify the general term
The \(n\)-th term of the sequence can be expressed as:
\[ T_n = \left(x^n + \frac{1}{x^n}\right)^2 \]
