So once you know the common difference in an arithmetic sequence you can write the recursive form for that sequence. However, the recursive formula can become difficult to work with if we want to find the 50 th term. Using the recursive formula, we would have to know the first 49 terms in order to find the 50 th.This sounds like a lot of work.

While we have seen recursive formulas for arithmetic sequences and geometric sequences, there are also recursive forms for sequences that do not fall into either of these categories. The sequence shown in this example is a famous sequence called the Fibonacci sequence.

Sum of Arithmetic Sequence Formula . The Arithmetic series of finite number is the addition of numbers and the sequence that is generally followed include – (a, a + d, a + 2d, …. and so on) where a is the first term, d is the common difference between terms.

Recursive and Explicit Formulas. In the previous section, you learned that a recursive formula tells you the value of each term as a function of previous terms. Here are the recursive formulas for arithmetic and geometric sequences:

Sal finds the recursive formula of the arithmetic sequence 4, 3⅘, 3⅗, 3⅖,... Sal finds the recursive formula of the arithmetic sequence 4, 3⅘, 3⅗, 3⅖,... If you're seeing this message, it means we're having trouble loading external resources on our website.

When dealing with sequences in math, both algebraic and geometric, we come across recursive rules. Watch this video lesson to learn how recursion works and how you can use a recursive rule to get ...
