Thus the right-hand side of the equation for the first endogenous variable includes no endogenous variables only exogenous variables. Recursive Formula If t 1 t 2 t 3t n is a set of series or a sequence. Recursion is an example of an iterative procedure.
Each term is found by doing something to the term s immediately in front of that term A recursive formula designates the starting term a1 and the nth term of the sequence an as an expression containing the previous term the term before it an-1.
We can say Recursion is an alternative way to looping statements. In a recursive formula each term is defined as a function of its preceding term s. Recursive formula for geometric sequence helps us find the next term of the sequence using the previous term only. These are called seed values.
