Question

Write a program to find out the sum of the series
1× x + x² + x² + .................. xn

Answer 1

Explanation:

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int i,n;

float x,sum=0;

clrscr(); //to clear the screen

printf(“1+x+x^2+……+x^n”);

printf(“nnEnter the value of x and n:”);

scanf(“%f%d”,&x,&n);

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

sum+=pow(x,i);

sum++;

printf(“nSum=%f”,sum);

getch(); //to stop the screen

}

Answer 2

the sum of the series

#include<iostream.h>

void main()

{

int 1, x, x²....;

float sum;

cout<<"enter the value for variables;

cin>>1>>x²>>...;

sum=(1+x²+x²+...);

cout<<"Sum="<<sum_of_series;

}
