In this video, we show you How to find the formula for a Quadratic Sequence to find the nth term by using a quadratic equation.
A Quadratic equation is of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. We will find the first and second difference of a sequence and set up a system of linear simultaneous equations to find the values of the constants; a, b, and c.
