Step 1: Identify the n th term (a n) of an arithmetic sequence and the common difference, d, Step 2: Put the values in the formula, a n+1 a n + d to find the (n+1) th term to find the successive terms. So to find the second term, we take the term before it (1) and double it. To find a recursive sequence in which terms are defined using one or more previous terms which are given. Given two terms in a geometric sequence find the 8th term and the recursive formula. Check out the "BUNDLE ARITHMETIC & GEOMETRIC SEQUENCES". A rule for how to find the next term of a sequence given a previous term For example, we could define a sequence this way: The first term is 1. Create a recursive formula by stating the first term, and then stating the formula to be the previous term plus the common difference. Each version has 20 questions written in 5 different formats. This worksheet drills the understanding of how to find the Explicit & Recursive Formula of a Geometric Sequence.įive different types of questions are drilled in this worksheet where students are asked to find the explicit and recursive formula given:
