Explicit And Recursive Formulas Youtube Introduces the concept of recursive and explicit formulas. discusses the pros and cons of using each type. 1. if you need to make the formula with a figure as the starting point, see how the figure changes and use that as a tool. 2. if you have an arithmetic sequence, the recursive formula is. a n 1 = a n d. 3. if you have a geometric sequence, the recursive formula is. a n 1 = a n ⋅ k. Let’s now try to form an explicit formula from a recursive one. consider the formula an = 2an−1 where a1 = 2 and n ≥ 2. to convert this to an explicit formula, let’s try to understand the pattern. let’s use the given formula to find the first four terms. the first term in the sequence is 2. then a2 = 2(2) = 4. Example 2. find an explicit formula for the nth term of the sequence 3, 7, 11, 15 and use the equation to find the 50 th term in the sequence. solution. an = 4n − 1, and a50 = 199. the first term of the sequence is 3, and the common difference is 4. an. = a1 d(n 1) an.

The recursive definition of a quadratic sequence has the form. the first part of the definition is the first term of the sequence: f (1) = 5. it's easy, but don't forget to write it down when you do problems on your test! the second part is almost as easy. remember that the second difference is equal to 2a, so just put the second difference in.
