Finding the nth Term in Arithmetic Sequences

The video tutorial explains how to determine the first term of a sequence and the constant rate of change. It then demonstrates how to find the zero term by reversing the rate of change. Finally, it shows the calculation of the 50th term using the rate of change and the zero term.
