We Want to Create a Class That Represents a Geometric

question 75

Multiple Choice

We want to create a class that represents a geometric sequence. A geometric sequence is a sequence of numbers that begin at some value and then multiplies each value by some constant to get the next value. For example, the geometric sequence 1, 2, 4, 8, 16 starts at 1 and multiplies each term by 2 to get the next. The geometric sequence 10.8, 5.4, 2.7, 1.35 starts at 10.8 and multiplies each term by 0.5 to get the next. The basic framework of a geometric sequence class is below: public class GeometricSequence
{
Private double initialValue;
Private double multiplier;
}
We want to create a geometric sequence using code like:
GeometricSequence first = new GeometricSequence (1, 2) ;
// Creates 1, 2, 4, 8, 16…
GeometricSequence second = new GeometricSequence (10.8, 0.5) ;
// Creates 10.8, 5.4, 2.7, 1.35 …
Which of the constructor specifications below will allow this code to behave as desired?

• A) public void GeometricSequence(double initial, double mult)
• B) public GeometricSequence init(double initial, double mult)
• C) public GeometricSequence GeometricSequence(double initial, double mult)
• D) public GeometricSequence(double initial, double mult)
