Examples
Common examples of arithmetic sequences
- even numbers: 2, 4, 6, 8, 10... (common difference is +2)
- odd numbers: 1, 3, 5, 7, 9... (common difference is +2)
- times tables: eg 5, 10, 15, 20, 25... (common difference is +5)
- moving at constant speed, eg walking the same distance every 10 minutes.
- shape patterns (like the image below):
