Lesson: 9.2 Arithmetic Sequences
Goal: Define arithmetic sequences and find summations DOD
Arithmetic Sequence: Sequence in which the difference of any two consecutive
terms is constant.
If , then there exists such that is called the common difference. nth Term of an Arithmetic Sequence Ch_9 Page 1 nth Term of an Arithmetic Sequence Sum of a Finite Arithmetic Sequence Why does this work? Examples
Is the sequence arithmetic? If so, find the common difference. Find the formula for
