Each time the value of n increases by 1, the value of an increases by a factor of 3. The 3rd choice is appropriate.

_____
When an expression like this one is written in plain text, it is appropriate (required) to put parentheses around the exponent that contains an arithmetic operation.
  an = 4·3^(n-1)

If you leave off the parentheses, the expression no longer describes a geometric sequence.

A fully inflated basketball has a radius of 12
valentinak56 [21]

The volume of air needed is equal to the volume of the sphere, which is 7,234.56 cm^3.

<h3>How to get the volume of a sphere?</h3>

The volume of air that we need is equal to the volume of the basketball.

Remember that for a sphere of radius R, the volume is:

V = (4/3)*3.14*R^3

In this case, the radius is 12cm, replacing that we get:

V = (4/3)*3.14*(12cm)^3 = 7,234.56 cm^3

Then, to fully inflate the ball, we need  7,234.56 cm^3 of air.
