The video tutorial explains recursive formulas, detailing how to determine the first term and the common difference to find subsequent terms. It provides examples with both negative and positive common differences, demonstrating how to apply the formula. The tutorial also covers writing recursive forms from given sequences, emphasizing the importance of identifying the first term and the common difference.

What does the recursive formula specify?

• The last term and how to find the next term

• The first term and how to find each subsequent term

• The common ratio and the first term

• The sum of all terms
