In this new section, you will learn about Arithmetic Sequences. After key terms such as Term and Common Difference, you will cover the Formula or the nth Term as well as the Equation for the nth Term. Arithmetic Means and four completed extra examples finish this lesson.
If you are given
several terms of a sequence, use the formula for the nth term to
find an algebraic expression for the nth term.
arithmetic means, first use the formula for the nth term to find d.
Then add d to the value before the unknown arithmetic means
repeatedly to find the missing means.
