a. write a program to create a finite arithmetic series and have the program ask
the user what the next number in the series is and checks it (with feedback).

b. write a program to calculate the sum of a series of numbers given the first
number and the definition of the series (i. e. the series equation).

c. write a program to create a finite geometric series.

d. write a program that will average 10 numbers.

e. write a program that will calculate and print the volume of a cube or a sphere
