![]() ![]() ![]() The tenth term could be found by multiplying the first term by the common ratio nine times or by multiplying by the common ratio raised to the ninth power. Using Recursive Formulas for Geometric Sequences A recursive formula allows us to find any term of a geometric sequence by using the previous term. Answer Button navigates to signup page Comment Button navigates to signup page (15 votes) Upvote. Can anyone explain the basic rules for them Thanks. Then each term is nine times the previous term. ![]() For example, suppose the common ratio is 9. Each term is the product of the common ratio and the previous term. The common ratio is multiplied by the first term once to find the second term, twice to find the third term, three times to find the fourth term, and so on. I find recursive sequences really, really confusing. Using Recursive Formulas for Geometric Sequences A recursive formula allows us to find any term of a geometric sequence by using the previous term. As with any recursive formula, the initial term must be given. This lesson will work with arithmetic sequences, their recursive and explicit formulas and finding terms in a sequence. ![]() Recursive formula is ana (n-1)xx1/5 In a Geometric sequence, the ratio of each term to its preceding term is always constant and is known as common ratio r. A recursive formula allows us to find any term of a geometric sequence by using the previous term.

Still, got questions? No problem! Don’t hesitate to comment below or reach out via email. For a geometric sequence with recurrence of the form a(n)ra(n-1) where r is constant, each term is r times the previous term. because bn is written in terms of an earlier element in the sequence, in this case bn1. Recursive Formula for Geometric Sequences The formula to find the nth term of a geometric sequence is: a n a n1 r for n2. Personally, I recommend looking at the arithmetic sequence or geometric sequence posts next! An example of a recursive formula for a geometric sequence is. The recursive formula calculates the next term of a geometric sequence, n+1, n + 1, based on the previous term, n. Looking to learn more about sequences? You’ve come to the right place!
