How do quadratic sequences work
WebMay 30, 2024 · Here's the sequence again in case you need it: The recursive definition of a quadratic sequence has the form. The first part of the definition is the first term of the sequence: f (1) = 5. It's easy, but don't forget to write it down when you do problems on your test! The second part is almost as easy. Remember that the second difference is ...
