Learn how to determine if a sequence is an example of an arithmetic sequence or not

The video tutorial explains how to determine if a sequence is arithmetic by checking for a common difference between terms. It highlights that if the difference is not consistent, the sequence is not arithmetic. The example used shows a sequence where the difference is not uniform, thus it is not an arithmetic sequence.
