# What is a geometric recursive formula?

## What is a geometric recursive formula?

Recursive formula for a geometric sequence is an=an−1×r , where r is the common ratio.

## What is a function in ActionScript?

Functions are blocks of code that carry out specific tasks and can be reused in your program. There are two types of functions in ActionScript 3.0: methods and function closures. Whether a function is a called a method or a function closure depends on the context in which the function is defined.

**When does a function need to be recursive?**

So we can say that, if the function requires the previous term to find the next term in the sequence, then the function is a recursive function. Most of the recursive functions will provide the beginning value of the sequence and the formula that helps to generate the next terms in the sequence.

### How does recursion work in a programming algorithm?

In a recursive algorithm, the computer “remembers” every previous state of the problem. This information is “held” by the computer on the “activation stack” (i.e., inside of each functions workspace). Every function has its own workspace PER CALL of the function.

### How to write a recursive formula for arithmetic?

Writing recursive formulas 1 The two parts of the formula should give the following information: 2 Therefore, the recursive formula should look as follows: 3 Check your understanding. 2) What is the recursive formula of the sequence ? 4 Reflection question. 5) Here is the general recursive formula for arithmetic sequences.

**When to use the preceding term in a recursive formula?**

A recursive formula always uses the preceding term to define the next term of the sequence. Sequences can have the same formula but because they start with a different number, they are different patterns.
