For example, the factorial function n! is defined by the rules. The numbers in the Fibonacci sequence are also known as Fibonacci numbers. In this tutorial, you'll focus on learning what the Fibonacci sequence. You will also explore some applications of recursively-defined sequences in biology, such as population growth, DNA replication, and phylogenetic trees. If we go with that definition of a recursive sequence, then both arithmetic sequences and geometric sequences are also recursive. For some sequences, it is possible to give an explicit formula for a n: this means that a n is expressed as a function of n. Thus, the arithmetic sequence recursive formula is: Arithmetic Sequence Recursive Formula. A recursive sequence is a sequence where the next terms use the previous terms.
