Step-by-step explanation:
A recursive rule allows us to find the term in a sequence from the previous term.
From the given geometric sequence find r the common ratio
r = =
= - 4
Hence recursive rule is
= - 4

The volume of the sawdust pile is 11,039.06 ft³.
<h3>What is the volume of the pile?The shape of the sawdust pile would be a cone. The diameter is always proportional to its height.
Diameter = k x height
where k is equivalent to the rate of increase of the diameter with respect to the increase in height.
25= k20
k = 25 / 20
k = 1.25
Diameter when height is 30 ft = 1.25x 30 = 35.50 feet
Volume of the sawdust = πr²h
Where:
x 3.14 x 18.75² x 30 = 11,039.06 ft³
