An arithmetic sequence is a series of numbers in which the difference between consecutive terms is constant. For example, 2, 5, 8, 11, 14 is an arithmetic sequence with a common difference of 3. The sum of an arithmetic sequence can be calculated using the formula: S = n/2 × (a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term.
