An arithmetic sequence is a sequence where each term is found by adding or subtracting the same value from one term to the next. This value that is added or subtracted is called "common sum" or "common difference" If the common difference is positive, the terms of the sequence will increa...

The formula provides an algebraic rule for determining the terms of the sequence. A recursive formula allows us to find any term of an arithmetic sequence using a function of the preceding term. Each term is the sum of the previous term and the common difference. For example, if the common...
An arithmetic series is the sum of the terms in an arithmetic sequence with a definite number of terms. Following is a simple formula for finding the sum:
An arithmetic series is the sum of the terms of an arithmetic sequence. The formula for the partial sum of an arithmetic sequence is Sn=n(a1+an)2Sn=n(a1+an)2How To: Given terms of an arithmetic series, find the partial sum Identify a1a1 and anan. Determine nn. Substitute values for...
