Finding nth Term of Sequences

The video tutorial explains how to derive a formula for the nth term of an arithmetic sequence. It starts by identifying the pattern of subtracting 3 between terms and then formulates a general rule using multiplication. The formula is further simplified using algebraic techniques, resulting in a concise expression for the nth term. The process is summarized to reinforce understanding.

What is the main goal of the problem discussed in the video?
