Learn how to find recursive formulas for arithmetic sequences. For example, find the recursive formula of 3, 5, 7,...

Learn how to convert between recursive and explicit formulas of arithmetic sequences. Before taking this lesson, make sure you know how to find recursive formulas and explicit formulas of …

Understanding Patterns: Recursive formulas show how each number in a sequence is calculated based on the previous one. This helps you recognize and understand number patterns.

Find the recursive formula of an arithmetic sequence given the first few terms.

A recursive formula defines terms of a sequence in relation to the previous value. As opposed to an explicit formula, which defines it in relation to the term number.

In this lesson, we'll be learning two new ways to represent arithmetic sequences: recursive formulas and explicit formulas. Formulas give us instructions on how to find any term of a …

Sal shows how to evaluate a sequence that is defined with a recursive formula. This definition gives the base case and then defines how to find the subsequent terms using the base case.

Sal is given an arithmetic sequence in explicit form and he converts it to recursive form. Then he does so the other way around!

The explicit formula of a sequence is the expression representing exactly the nth term of the sequence. Think of it as a function that inputs term number and outputs the value of that term …

You might be a little bit, a toss up on which method you want to use, but for sure this second method, right over here where we'd come up with an explicit formula once we know the initial …
