A recursive formula is a formula that requires the computation of all previous terms in order to find the value of a n. As with any recursive formula the first term must be given. Recursion in the simplest terms is a type of looping techniqueIt exploits the basic working of functions in R.
Thus this is the main difference between recursive and explicit.
For example to find the second term of any sequence we multiply the first term by the common ratio. As you can observe from the sequence itself it is an arithmetic sequence which includes the first term followed by other terms and a common difference d between each term is the number you add or subtract to them.
