1) Give examples to show how you can use the differences tables to work out the rule using n for the term number.
2) By looking at patterns, describe the rule using n for one of your linear patterens and for one of your quadratic patterns.

Look at the examples they gave you for the method of common differences. (There should be plenty in your book and / or in your class notes.)
Make up your own, similar, example. Show that the method works.
I'm not sure what they're after, here...? They told you to invent some examples, demonstrating that the method works. Now they're asking you to "describe" the rule you've already given "by looking at patterns"...? Sound circular...
Check your book for examples of what they're meaning here.
