Question
**Problem Statement:**

Find the integral:

\[
\int_{1}^{2} x^{-2} \, dx.
\]

**Hint:**

Choose \( x_i^* \) to be the geometric mean of \( x_{i-1} \) and \( x_i \) (that is, \( x_i^* = \sqrt{x_{i-1} x_i} \)) and use the identity:

\[
\frac{1}{m(m+1)} = \frac{1}{m} - \frac{1}{m+1}
\]

**Solution:**

Value of integral = [insert answer here]
