Traditionally, we denote the convolution by the star, and so convolving sequences a and b is denoted as ab.The result of this operation is called the convolution as well. The closed-form solution is a function of n which is obtained from the recursive relation which is a function of the previous terms f (n-1). Begin by finding the common ratio, r 6 3 2. The Recursive Sequence Calculator is an online tool that calculates the closed-form solution or the Recurrence equation solution by taking a recursive relation and the first term f (1) as input. Example 9.3.1: Find an equation for the general term of the given geometric sequence and use it to calculate its 10th term: 3, 6, 12, 24, 48.

Convolution is a mathematical operation on two sequences (or, more generally, on two functions) that produces a third sequence (or function). In fact, any general term that is exponential in n is a geometric sequence. The Algebra 1 course, often taught in the 9th grade, covers Linear equations, inequalities, functions, and graphs Systems of equations and inequalities Extension of the concept of a function Exponential models and Quadratic equations, functions, and graphs.
