What are Arithmetic and Geometric Sequences? A sequence is a group of numbers, called terms, arranged in a specific order. Arithmetic Sequences. Arithmetic sequences have a common difference. In other words the same value is added or subtracted from term to term. Example: 1, 3, 5, 7, 9, 11 (common difference is +2)
