An Arithmetic Sequence is one in which there is a constant adder between terms. Some textbooks reference this as a sequence in which there is a constant difference between terms. An example of an Arithmetic Sequence is as follows:

2. Find the common difference for the arithmetic sequence whose formula is ; an = 6n + 3 ... 11. The seating pattern is forming an arithmetic sequence. 60, 68, 76, ... We wish to find "the sum" of all of the seats. n = 20, a1 = 60, d = 8 and we need a20 for the sum. Now, use the sum formula: There are 2720 seats.
