Sequences are a special type of function that are useful for describing patterns. In this unit, we'll see how sequences let us jump forwards or backwards in patterns to solve problems.

This topic covers: - Recursive and explicit formulas for sequences - Arithmetic sequences - Geometric sequences - Sequences word problems

The sequences where you keep adding the same amount, we call these arithmetic sequences, which we will also explore in more detail. But to show that this is infinite, to show that we keep this pattern …

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 …

In this unit, we learn about the various ways in which we can define sequences. We'll construct arithmetic and geometric sequences to describe patterns and use those sequences to solve problems.

Sal introduces arithmetic sequences and their main features, the initial term and the common difference. He gives various examples of such sequences, defined explicitly and recursively. Created by Sal Khan.

Let's play with math patterns involving numbers, shapes, and variables before moving on to functions. We'll learn the basics, work with linear models, and experiment with both linear and nonlinear functions.

An arithmetic sequence creates each term by adding (or subtracting) a common value. A geometric sequence uses multiplication (or division) by a common value to create the next term.

What is the difference between an arithmetic sequence and a geometric sequence? In an arithmetic sequence, we add the same number to each term in order to get the next term in the sequence. In a …
