Question

follow the steps outlined in items a.-c. below.

A. Find an example of a statement that can be proven using mathematical induction from an outside resource.

B. Prove the example using mathematical induction and make sure to explain each step carefully in your own words.

C. Reflect on your experience in elaborating the proof and discuss what steps were the most difficult for you.

-->  use the image as the example 

The image shows a mathematical series and its sum:

\[
\frac{1}{1 \cdot 3} + \frac{1}{3 \cdot 5} + \frac{1}{5 \cdot 7} + \cdots + \frac{1}{(2n-1)(2n+1)} = \frac{n}{2n+1}
\]

This series involves adding fractions where each fraction's denominator is the product of consecutive odd numbers, beginning from 1 and 3, and increasing by two for each subsequent term. The expression on the right, \(\frac{n}{2n+1}\), represents the sum of the series. Here, \(n\) is a positive integer that determines the number of terms included in the series.
