GCSE Maths - Types of Number Sequences - Arithmetic vs Geometric #54

The video tutorial explains two main types of number sequences: arithmetic and geometric. Arithmetic sequences involve adding or subtracting a constant value, known as the common difference, to each term. Geometric sequences involve multiplying or dividing by a constant value, known as the common ratio. The tutorial provides examples of each type, demonstrating how to identify the pattern and calculate the common difference or ratio. It emphasizes checking the first few terms to confirm the sequence type and offers methods to verify the common ratio by dividing terms.

What should you do if you're unsure about the common ratio in a geometric sequence?

What is the common ratio of the sequence that starts with 27?

Describe the difference between arithmetic and geometric sequences.
