[[Block 1 introduction]] / [[Sequences overview]] / 1.1.2 Tabular representations # Tabular (and graphical) representations of arithmetic sequences Here we are only focusing on [[Arithmetic sequence]] sequences, presented in different forms. #### Need to be able to: - Understand that arithmetic sequences always have a [[Common difference]]. - Understand that arithmetic sequences can reduce in size. Negative can be difficult to show with representations. - Understand how pictorial representations and tables of numbers are linked. > [!success]- Demonstrate understanding > *Being able to answer questions like all of these is needed to show understanding:* > 1. > 2. >[!Example]- Vocabulary >*This vocabulary needs to be properly understood as part of this small step:* >- [[Difference]] >- [[Common difference]] >- [[Linear]] > [!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.* > > - **Understand tabular (and graphical) representations of arithmetic sequences** > - **Understand how graphical representations link to tabular form**
