Question

Please solve the following discrete math proof 

**Mathematical Induction Example: Sum of a Geometric Series** **A. Problem Statement:** Prove that if \( r \neq 1 \) is a real number, then for all integers \( n \geq 1 \), \[ 1 + r + r^2 + \cdots + r^n = \frac{1 - r^{n+1}}{1 - r}. \] **Explanation:** This problem involves proving a formula for the sum of a geometric series with \( n+1 \) terms, starting from \( r^0 = 1 \) and ending at \( r^n \). The formula shows how to express this finite series as a simple fraction when \( r \neq 1 \). - The left side of the equation represents the sum of a series of powers of \( r \). - The right side provides a way to calculate that sum using the formula \( \frac{1 - r^{n+1}}{1 - r} \). This is a classic example of using a mathematical formula to simplify the process of summing a series, and it's often proven using mathematical induction.
