Answer
A(n) = 0.3 + (n - 1)(-0.3)
Work Step by Step
The formula for an explicit expression is A(n) = A(1) + (n - 1)(d) (d represents the common difference)
All of the missing pieces in this equation are provided in the recursive equation in the question where the d value is the common difference and A(1) next to the equation.
D = -0.3
A(1) = 0.3
After we plug this in the explicit expression, we get the formula A(n) = 0.3 + (n - 1)(-0.3)
