To summarize the process of writing a recursive formula for a geometric sequence: 1. Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?2. Find the common ratio.The number you multiply or divide.

A recursive formula defines the value tn based on other values of the series. tn = a + (n-1)d is not recursive since tn increases by a fixed amount d which makes it an arithmetic sequence. You could write this recursively, though. tn = tn-1 + d, t1=a. But this is only trivially recursive since you can define tn as above without the recursion ...

Recursive Formula. For a sequence a 1, a 2, a 3, . . . , a n, . . . a recursive formula is a formula that requires the computation of all previous terms in order to find the value of a n. Note: Recursion is an example of an iterative procedure.

Using Explicit Formulas for Geometric Sequences. Because a geometric sequence is an exponential function whose domain is the set of positive integers, and the common ratio is the base of the function, we can write explicit formulas that allow us to find particular terms.

Is it possible to create a recursive formula? Hello all, This is my first post on this forum, so I apologize for any breaches in protocol, and I will endeavor to correct them. I have a large column of data in C1 from R1 to R5000. I would like to use the SUM function to analyze the data.
