AP Precalculus | Change in Arithmetic and Geometric Sequences | Explicit Formula | The Easy Way! #maths #education #viralvideo #apprecalculus

This Algebra 1 topic is also revisited in AP Precalculus, so the title comes as no surprise.

🔢 In this video, you'll learn how to identify and describe the change in both arithmetic and geometric sequences — a foundational skill in understanding patterns, growth, and structure in mathematics. Whether you're just being introduced to sequences or reviewing for a test, this lesson will walk you through how these sequences work, how to find the rate or ratio of change, and how to describe each sequence in simple terms.

🔍 What You’ll Learn:
The difference between arithmetic sequences (adding/subtracting the same number) and geometric sequences (multiplying/dividing by the same number)

How to find the common difference in an arithmetic sequence

How to find the common ratio in a geometric sequence

How to identify whether a sequence is arithmetic, geometric, or neither

How to write and describe the nth term or explicit rule for each type of sequence

How to apply these patterns to real-world problems and data

Helpful strategies and tips to avoid common mistakes when analyzing sequences

💡 Why This Video Is Helpful:
Supports learning for Algebra 1, Algebra 2, and Pre-Algebra

Aligned with common curriculum standards and great for STAAR, EOC, SAT, ACT prep
