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:
