The recursive rule is

.
The iterative rule is

The recursive rule is given by the formula

, where d is the common difference. Our common difference is -4, which gives us the recursive rule above.
The iterative rule begins with the formula

, where a₁ is the first term and d is the common difference. Our first term is 10 and our common difference is -4:
