[[Block 1 introduction]] / [[Sequences overview]] / 1.1.4 Describe simple patterns # Describe simple patterns with a term-to-term rule #### Need to be able to: - Describe arithmetic sequences with a starting point (first term) and the term-to-term rule - Understand that some rules are abstract and others are connected to specific situations. For example, the number of people who can sit around tables of different sizes. - Be able to extend sequences using the term-to-term rule and find missing terms. > [!success]- Demonstrate understanding > *Being able to answer questions like all of these is needed to show understanding:* > 1. Draw a pattern with a term-to-term rule of +4. > 2. What rule is represented by the sequence: **100, 89, 78, 67…** > 3. What rule is shown in this representation: > ![[Pasted image 20250528181234.png]] >[!Example]- Vocabulary >*This vocabulary needs to be properly understood as part of this small step:* >- [[Arithmetic sequence]] >- [[Term to term rule]] > [!warning]- Misconceptions > *These are things that people commonly misunderstand about this small step.* > [!Extension]- > *Extension is about digging deeper into the concept(s) in the small step, not introducing new or 'harder' content. Learning later content is easier if understanding is deeper.* > > - **Explore term-to-term rules for other types of sequences**
