Finding the Term Formula of an Arithmetic Progression

The video tutorial explains arithmetic progressions, also known as linear sequences, where terms increase or decrease by a constant amount. It provides examples of arithmetic progressions and non-examples, illustrating the concept of a common difference. The tutorial outlines a step-by-step process to find the n-th term formula of a sequence, using examples to demonstrate the method. The video concludes with a summary of key points and encourages viewers to apply the process to find the n-th term of sequences.

Provide an example of a sequence that is not an arithmetic progression and explain why.

How do you adjust the n-th term formula after finding the common difference?

What is the significance of the constant in the n-th term formula?
