How Do You Determine If A Sequence Is Arithmetic Or Geometric?

Real math help. How Do You Determine if a Sequence is Arithmetic or Geometric? How Do You Determine if a Sequence is Arithmetic or Geometric?

Note:

You have a pattern in your sequence. Great! Think it might be an arithmetic or geometric sequence? If the sequence has a common difference, it's arithmetic. If it's got a common ratio, you can bet it's geometric. Practice identifying both of these sequences by watching this tutorial!

    How Do You Find the Next Terms in an Arithmetic Sequence?

    To find the next few terms in an arithmetic sequence, you first need to find the common difference, the constant amount of change between numbers in an arithmetic sequence. Once you know the common difference, you can use it to find those next terms! This tutorial takes you through that process, so be sure to check it out!
