How to find the rule of a arithmetic sequence given two values in the sequence

The video tutorial explains how to solve a mathematical problem involving sequences. It begins by setting up the problem with given values and demonstrates how to find the difference between them. The instructor then solves for the value of Ace of 1 using a formula. Finally, the tutorial derives a general rule for the sequence, providing a step-by-step explanation of the process.

Explain the significance of finding the difference in the context of this problem.

What would happen if you used Ace of 13 instead of Ace of 7 in the calculations?

What is the final rule derived from the calculations involving Ace of N?
