Finding nth Terms of Sequences

The video tutorial covers the concept of sequences and nth terms, focusing on linear sequences that increase by a constant number. It explains how to determine the nth term using examples like the four and three times tables. The tutorial also demonstrates how to calculate specific terms in a sequence using the nth term formula. Practice questions are provided to reinforce understanding.
