Write the nth term of a linear sequence
In this lesson, we will investigate what a linear sequence is, and how to calculate an algebraic rule to generate the sequence, referred to as the nth term.

Find terms of a linear sequence
In this lesson, we will investigate how to take an algebraic rule and generate a sequence, or specific terms within a sequence.
Triangular and Fibonacci style sequences
In this lesson, we will be learning about triangular and Fibonacci style sequences. We will use arrays to aid visualising how sequences expand.
Simple quadratic and cubic sequences
In this lesson, we will investigate how terms change when a sequence is quadratic. In other words, it is of the form ax² + bx + c. We will also investigate cubic sequences.
