Two Methods for Finding the Nth Term of an Arithmetic Progression

The video tutorial explains two methods for finding the NTH term of an arithmetic progression or linear sequence. It focuses on an algebraic approach, detailing how to derive the NTH term formula by considering the first term and the common difference. The tutorial provides examples with different sequences to illustrate the method and concludes with advice on using both methods based on personal preference.
