It is, however, most common to divide the second term by the first term because it is often the easiest method of finding the common ratio. We can divide any term in the sequence by the previous term. The common ratio is also the base of an exponential function as shown in Figure 2ĭo we have to divide the second term by the first term to find the common ratio? Given a term in an arithmetic sequence and the common difference find the recursive formula and the three terms in the sequence after the last one given. The sequence of data points follows an exponential pattern. Substitute the common ratio into the recursive formula for geometric sequences and define. The common ratio can be found by dividing the second term by the first term. Write a recursive formula for the following geometric sequence. Substitute the common ratio into the recursive formula for a geometric sequence.ģ Using Recursive Formulas for Geometric Sequences.Find other quizzes for Mathematics and more on Quizizz for free Skip to Content.
