Risha, Devin and Alice each create a number pattern. Risha: \( 15,18,21,24,27,30 \ldots \) Devin: \( 15,16,18,21,25,30 \ldots \) Alice: \( 50,47,44,41,38,35 \ldots \) a. State one difference between Devin's pattern and Alice's pattern. State one similarity between Risha's

### a. **Difference between Devin's pattern and Alice's pattern** - **Direction of Change:** - **Devin's Pattern:** The numbers are **increasing**. For example, from 15 to 16 (+1), then to 18 (+2), and so on. - **Alice's Pattern:** The numbers are **decreasing**. For example, from 50 to 47 (−3), then to 44 (−3), and so on. **Summary:** Devin's pattern **increases** by varying amounts, while Alice's pattern **decreases** by a constant amount. --- ### b. **Similarity between Risha's pattern and Devin's pattern** - **Starting Number:** - **Risha's Pattern:** Starts with **15**. - **Devin's Pattern:** Also starts with **15**. **Summary:** Both Risha's and Devin's patterns **begin with the number 15**.
