in C++

Recall that a GP is specified by two terms a and r. The first term of the sequence is a, and the r is by how much multiply each term to get the next term. So the first N terms of the above AP will be:

2 n-1 a, ar ar , . . . , ar

Suppose, for example, that a = 4, r = 0.5, and n = 6. Then this function should return the string

"4,2,1,0.5,0.25,0.125"

// Return a string of the form n1,n2,n3,... for the given GP. string get_gp_terms

(double a, double r, size_t n)

{

// TODO - Your code here
