Arithmetic Sequences
Arithmetic sequences are those that increase by a constant difference from term to term. For example, the sequence 1, 5, 9, 13 has a first term of 1 and a common difference of 4. A sequence is different from a function in that the terms of a sequence are discrete and not continuous. These sequences can be studied in the abstract for analysing patterns or they can be used to describe patterns that occur in context....
