# How do you find the recursive formula for a quadratic equation?

**recursive equation**for the original

**quadratic**sequence is then easy. More precisely, if the

**quadratic**sequence is given by q(n), where q is a

**quadratic**polynomial, then d(n)=q(n+1)−q(n) is the arithmetic progression given by d(n)=an+b, where a is the second difference and b=d(0).

Keeping this in view, how do you find the recursive formula?

Find the common difference. (The number you add or subtract.) 3. Create a **recursive formula** by stating the first term, and then stating the **formula** to be the previous term plus the common difference.

Similarly, what is a recursion formula? A General Note: **Recursive Formula** A **recursive formula** is a **formula** that defines each term of a sequence using preceding term(s). **Recursive formulas** must always state the initial term, or terms, of the sequence.

People also ask, what is the recursive formula for the geometric sequence?

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

What is the definition of recursive formula?

**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. See also.
