The \(n\)th term for a quadratic sequence has a term that contains \(n^2\). Terms of a quadratic sequence can be worked out in the same way. Write the first five terms of the sequence \(n^2 + 3n - 5\) ...

For a quadratic sequence, the differences between terms are not the same (these are known as first differences), but the differences between those differences are the same (these are known as second ...
