Quadratic sequences can also be called quadratic algebraic sequences. Here are two examples of quadratic sequences: 4, 7, 12, 19, 28 requires adding to work out that the second difference is +2. and. 1, −4, −15, −32, −55 requires subtracting to work out that the second difference is −6.

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...
Work out the sequences of first and second differences. Note: check that the first differences are not constant and the second differences are constant, to make sure you have a quadratic sequence! e.g. sequence: 1, 10, 23, 40, 61. first difference: 9, 13, 17, 21, ...
A quadratic nth term is a rule used to generate a sequence based on the square numbers and has the general form an^{2}+bn+c where a, b, and c are constants (a constant is a number that does not change).
A quadratic sequence is a sequence whose n^{th} term formula is a quadratic i.e. it has an n^2 term, so takes the form, \textcolor{red}{a}n^2+\textcolor{blue}{b}n+\textcolor{limegreen}{c} , where a, b, and c are all numbers.
