Algorithm:

• Start.

• Declare variables i, j and Sum.

• Read values of numbers.

• Set i = 1 and j = 1.

• Increment i and set j = j + 2.

• Add numbers and assign the result to sum.

• Sum = Sum + (float)(j)/(j+1).

• Display sum.

• Stop.

Program:

#include<stdio.h>
#include<conio.h>

int main(){
int i, j, n;
float sum = 0;

printf("\n Enter the Value of n:");
scanf("%d",&n);

for(i=1, j=1; i<=n; i++, j=j+2){
sum = sum+(float)(j)/(j+1);
}
printf("sum= %f",sum);
}

Output:

Enter the Value of n: 5

Sum = 3.858333
