How can I write this program in C++ language?

Question

Write a program that takes the first term and the magnitude of the ratio of a geometric progression and then
a) Calculate the sum M of the first sentence. Make sure that M is taken from the user

b) Calculate the value of the sentence K. Pay attention that K is received from the user.

Answer 1

Schindlabua The sentence means the same number of numbers

Answer 2

The geometric progression formula is `a * (1 - r^n) / (1 - r)`, where `a` is the initial term and `r` the ratio. I'm not sure what is meant by the word "sentence".
