Learn how to write the explicit formula given two values of an arithmetic sequence

The video tutorial explains how to solve a mathematical problem involving sequences. It begins by setting up the problem and identifying the given values. The instructor then explains the correspondence between different terms in the sequence and demonstrates how to substitute these values into an explicit formula. The tutorial continues by solving for the difference D and finding the first term of the sequence. Finally, the instructor derives and simplifies the explicit formula, emphasizing the importance of understanding the relationships between terms and using formulas effectively.
