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.

An explicit formula allows us to calculate the value of any term in the sequence by plugging in the term number, while a recursive formula defines each term in the sequence in relation to the …

Learn how to find explicit formulas for arithmetic sequences. For example, find an explicit formula for 3, 5, 7,... Before taking this lesson, make sure you are familiar with the basics of arithmetic …

Sal finds terms of arithmetic sequences using their explicit and recursive formulas.

Sal finds explicit formulas of arithmetic sequences given the first few terms of those sequences. He also explores equivalent forms of such formulas.

Practice Relating linear contexts to graph features Get 5 of 7 questions to level up!

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.

This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing …

They explore many examples of functions and their graphs, focusing on the contrast between linear and exponential functions. They interpret functions given graphically, numerically, …

Whichever way you start numbering, it is always important to check that your formula for the sequence actually ends up with the sequence that you want. If you start at a (1), you will …
