Writing Recursive Equations for Linear Relationships

The video tutorial explains how to write recursive equations for linear relationships. It begins with an introduction to recursive equations, which use previous values to determine a pattern. The first example demonstrates an increasing pattern where each value is the previous value plus three. The second example shows a decreasing pattern where each value is the previous value minus five. The video concludes with encouragement to engage with the content and apply the concepts learned.

What is a recursive equation?

• An equation that defines a sequence based on a constant value.

• An equation that defines a sequence based on the next term.

• An equation that defines a sequence based on random values.

• An equation that defines a sequence based on the previous term.

What is the recursive equation for the first example?

• f(0) = 8, f(x) = f(x-1) - 3

• f(0) = 8, f(x) = f(x-1) + 3

• f(0) = 3, f(x) = f(x-1) - 8

• f(0) = 3, f(x) = f(x-1) + 8
