Arithmetic Sequences
Use the following formula to find any term of an arithmetic sequence. an = the term in the sequence you are trying to find (n represents the desired term number) a1 = the first term in the sequence. d = the common difference. Example: What is the 10th term of the following sequence? 1, 5, 9, 13, … So the 10th term of this sequence is 37. Example:
