To determine whether the formula = + 3 with = 5 is explicit or recursive, let's break down what each type of formula means and then apply these concepts to the given formula.
Explicit Formula: An explicit formula provides a direct calculation for the n-th term of a sequence using alone. You can compute directly without referring to any previous terms in the sequence.
Recursive Formula: A recursive formula defines each term in the sequence based on one or more previous terms. It typically involves:
A base case (or initial condition) that provides the value of the first term (or terms).
A recursive rule that shows how to calculate from the previous term(s), such as , and possibly other earlier terms.
