How do you find an arithmetic sequence
WebSome arithmetic sequences are defined in terms of the previous term using a recursive formula. The formula provides an algebraic rule for determining the terms of the … WebAn 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 d, ... } Example 1
