![**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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2a4cecdd-94f1-45ae-b6d2-43e39cc00a4c%2Fa663bb94-8803-491f-9303-9a7ab56e974a%2Fak7zjg_processed.png&w=3840&q=75)
