Sequences Activity
The below QuickQuestion Interface © generates random sequences and their nth terms.
By clicking on the various boxes, you can hide/reveal different information, and so test various different aspects of working with sequences.
Hide the orange boxes, and see if you can work out the nth term from the terms of the sequence.
Hide the blue boxes and calculate the terms from the rules.
Or hide a mixture, and see how many you can work out.
What is the minimum amount of information needed to work out all the rest?

Ideas for Teachers
This one is a little bit different, and gives you full control over what information you hide and show the students.
Start with simple questions, by the orange and last 2 blues, and ask what the next 2 terms are.
Reveal the rule and the first blue box only, and get them to work out the rest. What if it was another blue box?
Reveal two adjacent terms only. What information do you need to assume to work the rest out?
For a linear sequence, can you work out the missing blue boxes if you reveal only 2 blue boxes that are not next to each other?
These are just some ideas to get you going with this activity designed to make students think in a different way.
