WebArithmetic Sequence. An arithmetic sequence is a sequence that has the property that the difference between any two consecutive terms is a constant. This constant is called the common difference. If a 1 is the first term of an arithmetic sequence and d is the common difference, the sequence will be: { a n } = { a 1, a 1 + d, a 1 + 2 d, a 1 + 3 ... WebThe arithmetic sequence formula is: Where, an an is the nth term (general term) a1 a1 is the first term n n is the term position d d is the common difference We get the arithmetic sequence formula by looking at the following example: We can see the common difference (d) (d) is 6 6, so d=6 d = 6. a1 a1 is the first term which is 3 3
