Induction

**Mathematical Proof Problem for Educational Purposes**

**Objective:** Prove that for all \( n \geq 2 \):

\[
1 + \frac{1}{4} + \frac{1}{9} + \cdots + \frac{1}{n^2} < 2 - \frac{1}{n}
\]

**Instructions:** 

You are required to show the inequality holds by induction or any other suitable mathematical technique. Start by testing the base case, \( n = 2 \), and proceed with a logical argument to demonstrate that the expression is true for all integer values greater than or equal to 2.

**Note:** This problem involves understanding the summation of reciprocals of perfect squares and comparing it with a decreasing linear function. Consider representing terms with known inequalities or other mathematical series expansions if needed.

**Discussion and Examples:** 

- Begin with known mathematical assertions or series comparisons.
- Think about how the series converges and its upper bound estimates.
- Utilize graphical representations or mathematical simulations, if possible, to illustrate the inequality visually.

This task is intended to strengthen problem-solving skills and understanding of series and inequalities.
