Quadratic Sequences. 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.
Quadratic sequence formula. The quadratic sequence formula is: an^{2}+bn+c . Where, a, b and c are constants (numbers on their own) n is the term position. We can use the quadratic sequence formula by looking at the general case below: Let’s use this to work out the n^{th} term of the quadratic sequence, 4, 5, 8, 13, 20, ...
