Learn to write the explicit formula given two terms of the sequence

The video tutorial explains how to find the common difference in arithmetic sequences, especially when terms are not consecutive. It introduces the explicit formula and demonstrates how to use it to solve for the common difference and find the first term. The tutorial also covers simplifying the explicit formula once the common difference and first term are known.
