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 \(n^2 + 3n - 5\) ...

Quadratic sequences are sequences that include an \(n^2\) term. They can be identified by the fact that the differences in-between the terms are not equal, but the second differences between terms are ...
