[[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.*
