Differentiating Arithmetic and Geometric Sequences

This video tutorial explains the differences between arithmetic and geometric sequences. It covers the concept of a common difference in arithmetic sequences and a common ratio in geometric sequences. The video also demonstrates how these sequences can be represented graphically, with arithmetic sequences forming a straight line and geometric sequences forming a curve. The tutorial concludes with a summary of the key differences between the two types of sequences.
