Find the Sum of the Convergent Series:

              2 + 0.5 + 0.125 + 0.3125

CODE in C:

#include<stdio.h>

float sum(float a, float r, float n) {

    float sum = 0;

    int i;

    for(i=0;i<n;i++) {

        sum = sum + a;

        a =a * r;

    }

    return sum;

}

int main() {

    float answer = sum(2,0.25,4);

    printf("Sum= %0.2f",answer);

    return 0;

}

OUTPUT:
