I created this classifying sequences activity to give my algebra students practice distinguishing between geometric and arithmetic sequences. I also threw in some other sequences which we classified as “neither.” On top of classifying the sequence, students also had to identify the next term in the sequence.

My original plan was to make this a color-coding activity, but I ended up giving up on that idea!

For next year, I think I would like to tweak it a bit and add some Fibonacci sequences into this activity! Maybe I should add Fibonacci as a separate type of sequence for my students to learn.
