Why it matters
- Recognize arithmetic vs. geometric patterns fast.
- Use explicit and recursive rules to model repeated change.
- Compute finite series (like totals, savings, and step-by-step growth).
- Understand infinite series ideas that show up in advanced math.
- Connect patterns to prediction and real decision-making.
- Build strong foundations for SAT/ACT and pre-calculus.
Tip: Arithmetic adds a constant — geometric multiplies by a constant.
