If n 1 term 12 3 1 3 4. The solutions are x0 x-4 and x-2. Sequence 9 28 57 96.
Gamma function here for the widget in this problem to one.
Also it can identify if the sequence is arithmetic or geometric. First lets find a. We learn how to use the formula as well as how to derive it using the difference method. When trying to find the nth term of a quadratic sequence it will be of the form an 2 bn c where a b c always satisfy the following equations 2a 2nd difference always constant.
