Number Patterns & Sequences (Arithmetic & Geometric)
This lesson covers:
- The two types of number sequences: arithmetic and geometric
- Arithmetic sequences are those where a 'common difference' added each time
- Geometric sequences are those where each term is multiplied by a 'common ratio' each time
What is the pattern in the following sequence:
Subtracting 5 each time
Adding 5 each time
Multiplying by 5 each time
Dividing by 5 each time
