WebThe formula for the nth term of an arithmetic sequence is a_n = a_1 + (n-1)d, where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and d is the common difference. What is an arithmetic Sequence? An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed number to the previous term. WebSal finds an explicit formula of a geometric sequence given the first few terms of the sequences. Then he explores equivalent forms the explicit formula and finds the corresponding recursive formula.
