Question

Write a program to input the value of x and n and print the sum of the following series L 1 + x + x2 + x3 + x4 + X5 1-x+x²-x3+x4 -85 YN *-+*+ X- XN Determine whether a number in + 2 3 N​

Answer 1

Answer:

Explanation:

#include <stdio.h>

#include <math.h>

int main()

{  

int sum =1, x, n, i;

printf("Here we will calculate the sum of series 1+ x + x^2+ ...+ x^n \n");

printf("Enter the value of x: ");

scanf("%d", &x);

 

printf("Enter the value of n: ");

scanf("%d", &n);

 

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

{

 sum+=pow(x,i);

}

 

printf("The sum of the series is: %d", sum);

return 0;
