Answer:
an = 36 + -4(n - 1)
Explanation:
Explicit formula:

Where:
- an = nth term
- a1 = first term
- d = common difference
Here, we are given the following:
The first term is 36
To get to the next term, 4 is subtracted from the previous term so the common difference is -4.
So we have:
- First term(a1) = 36
- Common difference = -4
By plugging this into

We acquire :
