Understanding Sequences and Patterns

Miss P introduces a unit on patterns, covering arithmetic, geometric, and other patterns. She explains arithmetic patterns as sequences formed by adding or subtracting a constant, and geometric patterns as sequences formed by multiplying or dividing by a constant. Other patterns, like the alphabet, don't fit these categories. Definitions of sequences and terms are provided, along with explanations of recursive and explicit formulas for finding terms in sequences. The video concludes with a review, encouraging students to revisit the material for better understanding.

What is the main focus of the unit introduced in the video?

• Statistics
