Math tutorial for how to find the common difference of a sequence

The video tutorial explains arithmetic sequences, focusing on the concept of a common difference. It begins with an introduction to arithmetic sequences, emphasizing the importance of having a consistent difference between terms. The tutorial then details how to calculate the common difference using examples, demonstrating that if the difference is consistent, the sequence is arithmetic. The video concludes by confirming the sequence as arithmetic with a common difference of five.

Explain the process of determining if a sequence is arithmetic.
