The recursive equation of the explicit equation is A(n) = A(n - 1) - 4, A(1) = -1

How to determine the recursive equation

From the question, we have the following parameters that can be used in our computation:

An = -4n + 3

Set n = 1, 2 and 3

A(1) = -4(1) + 3 = -1

A(2) = -4(2) + 3 = -5

A(3) = -4(3) + 3 = -9

In the above sequence, we can see that -4 is added to the previous term to get the new term

So, we have the recursive equation to be

A(n) = A(n - 1) - 4, A(1) = -1
