### Geometric Series - Independent Practice #1

1. **Problem Statement:**
   - When a rubber ball is dropped from a height of 1,280 centimeters, the heights in centimeters of the first few bounces form a geometric sequence:
     - 960, 720, _______, _______

   a) **Question:** What is the common ratio of this sequence?

   **Answer Box:**
   - [ ]

2. **Follow-Up Question:**
   - Find the heights of the third and fourth bounces.

**Explanation for Teachers and Students:**

This exercise focuses on understanding and calculating the terms of a geometric sequence. A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

**Given Sequence:**
- First term (\(a_1\)) = 1280 cm
- Second term (\(a_2\)) = 960 cm
- Third term (\(a_3\)) = 720 cm

To solve part (a), you need to find the common ratio (\(r\)) using the terms provided. Once the common ratio is determined, apply it to find the missing terms in the sequence.

**Mathematical Approach:**
1. **Calculate the Common Ratio:**
   \(r = \frac{a_2}{a_1} = \frac{960}{1280} = 0.75\)
   
   \(r = \frac{a_3}{a_2} = \frac{720}{960} = 0.75\)

2. **Identify the Missing Terms:**
   - Third term (\(a_4\)): \(720 \times 0.75\)
   - Fourth term (\(a_5\)): \(a_4 \times 0.75\)

By following these steps, students will be able to complete the sequence and identify the common ratio correctly. Encourage them to practice with different sequences to reinforce their understanding of geometric progressions.
