Question

write a program to find the sum of the following series x+x2+x3+x4 ........x10,5+10+15+20..........100​

Answer 1

Answer:

// C program to get the sum of the series

#include <math.h>

#include <stdio.h>

// Function to get the series

double Series(double x, int n)

{

double sum = 1, term = 1, fct, j, y = 2, m;

// Sum of n-1 terms starting from 2nd term

int i;

for (i = 1; i < n; i++) {

fct = 1;

for (j = 1; j <= y; j++) {

fct = fct * j;

}

term = term * (-1);

m = term * pow(x, y) / fct;

sum = sum + m;

y += 2;

}

return sum;

}

// Driver Code

int main()

{

double x = 9;

int n = 10;

printf("%.4f", Series(x, n));

return 0;

}
