![]() To use recursive and explicit formulas to find terms in a sequence. The common difference of the given sequence is,ĭ = 2 - (-4) (or) 8 - 2 (or) 16 - 8 =. (Recursive Formula) Objectives: To write recursive (and explicit) formulas for arithmetic sequences. Using Arithmetic Sequence Recursive Formula? To obtain the third sequence, we take the second term and multiply it by the common ratio. Then we multiply the first term by a fixed nonzero number to get the second term of the geometric sequence. To generate a geometric sequence, we start by writing the first term. A recursive definition must be repeated over and over to create the sequence. How to Derive the Geometric Sequence Formula. ![]() What Is the n th Term of the Sequence -4, 2, 8, 16. Recursive Definition (Formula) of a Sequence In order to describe a sequence to someone, we simply must tell them where to start, and then how to get the next term of the sequence.
