As we have started C Programming coding with Example Series, We have published last post Write A Program To Find SUM of AP. We have chosen to start with mathematical series and in this post you will find some basic idea and some useful concepts about Geometric Progression (G.P.).You can download C Codes below.Please let us know your feedback.

Geometric Progression Basic Guide:-A sequence of non-zero numbers is a Geometric Progression (G.P.) if the ratio of any term and its preceding term is always constant.

A Geometric Progression (G.P.) is given by a, ar, ar

where a = the first term , r = the common ratio

Geometric Progression Basic Guide:-A sequence of non-zero numbers is a Geometric Progression (G.P.) if the ratio of any term and its preceding term is always constant.

A Geometric Progression (G.P.) is given by a, ar, ar

^{2}, ar^{3}, ...where a = the first term , r = the common ratio

Examples for Geometric Progressions

1, 3, 9, 27, ... is a geometric progression (G.P.) with a = 1 and r = 3

2, 4, 8, 16, ... is a geometric progression (G.P.) with a = 2 and r = 2

Geometric Mean of an Geometric Progression (G.P.)

Write A Program In C To Find SUM of Geometric Progression-Series- Sequence:

#include<stdio.h>

int main(){

float a,r;

float sum=0;

printf("Enter the first number of the G.P. series: ");

scanf("%f",&a);

printf("Enter the common ratio of G.P. series: ");

scanf("%f",&r);

if(1 > r)

sum = a/(1-r);

else

sum = a/(r-1);

printf("\nSum of the infinite G.P. series: %f\n\n",sum);

delay(5000);

return 0;

}

int main(){

float a,r;

float sum=0;

printf("Enter the first number of the G.P. series: ");

scanf("%f",&a);

printf("Enter the common ratio of G.P. series: ");

scanf("%f",&r);

else

sum = a/(r-1);
