Understanding Sequences and Costs

In this video tutorial, Mrs. Cox introduces students to the concept of patterns and sequences in mathematics. The lesson covers identifying patterns through addition, subtraction, multiplication, and division. Students learn to apply these concepts to solve real-world problems, such as cost comparison exercises. The tutorial concludes with advanced pattern exercises to reinforce learning.
