Inductive Reasoning: Sequences and Series

The video tutorial explains how to find the nth term in a sequence where each term increases by 3, starting from 6. The instructor identifies the pattern and derives a general expression for the nth term as 3(n + 1) or 3n + 3. The expression is verified for different terms to ensure its accuracy.
