Given a sequence of numbers determine if it is geometric or not

The video tutorial explains how to determine if a sequence is geometric by checking if the ratio between consecutive terms is constant. It provides a step-by-step verification process using examples, demonstrating that if the ratio remains the same, the sequence is geometric. The tutorial concludes with a brief mention of further examples to be explored.

Explain how you would verify that a sequence is geometric.

Calculate the common ratio if the first four terms of a sequence are 2, 4, 8, and 16.
