Introduction to Common Sequences: Triangular, Square, and Cube Numbers

The video tutorial introduces three common types of sequences: triangular numbers, square numbers, and cube numbers. It explains how these sequences are derived from geometric patterns. Triangular numbers are visualized using snooker balls arranged in a triangle, square numbers are explained through geometric squares, and cube numbers are illustrated by building cubes. The tutorial emphasizes recognizing these sequences and understanding their patterns.
