The interest gets added to the amount invested, so the next year Sam gets interest on the interest already earned, as well as on the original amount. To get the next term, we multiply the term we're on by r = 2. For example, if the 5th term of a geometric sequence is 64 and the 10th term is 2, you can find the 15th term. A series is a special type of sequence: a How to Find Any Term of a Geometric Sequence. Geometric Sequences and Exponential Functions. Calculate the percentage of route climbing if the horizontal distance places A, B is 7. Since the common ratio is the number being multiplied by to get each next term it gives a constant percent change in the outpus. Each number in the sequence is called a term (or sometimes "element" or "member"), read Sequences and Series for more details. 1 Identify arithmetic and geometric sequences · P.
