What is r? We say geometric sequences have a common ratio. Geometric sequences are important to understanding geometric series.ĭetermine the nth term of a geometric sequence.ĭetermine the common ratio of a geometric sequence.ĭetermine the formula for a geometric sequence.Ī geometric sequence is a sequence that has the pattern of multiplying by a constant to determine the consecutive terms. Homework problems on geometric sequences often ask us to find the nth term of a sequence using a formula. As an example, the following sequence does not have a common difference, so it is not an arithmetic sequence. Each term after the first term is obtained by multiplying the previous term by r, the common ratio. is arithmetic, because each step subtracts 4. is arithmetic, because each step adds three and 7, 3, 1, 5. An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value. How much money do you have in the bank after 3 years You invest 5000 for 20 years at 2 p.a. Jennifer Freidenreich Diablo Valley College Geometric sequences have a common ratio. Purplemath The two simplest sequences to work with are arithmetic and geometric sequences. You leave the money in for 3 years, each year getting 5 interest per annum. Sequences whose rule is the multiplication of a constant are called geometric sequences, similar to arithmetic sequences that follow a rule of addition.
