How do you find the formula for the nth term of an arithmetic sequence

The video tutorial explains how to find the general formula for an arithmetic sequence using given terms. It starts by identifying the common difference between terms and then calculates the first term. Finally, it derives the formula for the nth term, demonstrating the process with examples.

Describe how the distributive property is applied in deriving the final formula for the nth term.
