Geometric Sequence Challenge
Problem Statement:

Run the program, then find the common ratio for the geometric sequence and enter it into the box.

```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double x1;
double num2;
double x2;
double x3;
double x4;
double x5;
CPlot plot;
int count;

//plot.backgroundImage("starryNight.png");
x1 = randint(0, 25);
num2 = randint(-20, 20);
x2 = x1 * num2;
x3 = x2 * num2;
x4 = x3 * num2;
x5 = x4 * num2;
printf("Please enter the common ratio for the geometric sequence: " + string_t(x1) + ", " + string_t(x2) + ", " + string_t(x3) + ", " + string_t(x4)+"\n");
count = 0;
while(count < 20) {
plot.strokeColor(randcolor());
plot.star(randdouble(-12, 24), randdouble(-12, 24), 5, 0);
count = count + 1;
}

plot.text("Incorrect. The correct answer is:", PLOT_TEXT_LEFT, -8, 6);
plot.text(num2, PLOT_TEXT_LEFT, 4, 4);
}
