n2.x2+1/x2=n find x3+1/n3.x3​

Answer 1

// C++ program to find sum of series

// 1 + x^2/2 + x^3/3 + ....+ x^n/n

#include <bits/stdc++.h>

using namespace std;

// C++ code to print the sum

// of the series

double sum(int x, int n)

{

double i, total = 1.0, multi = x;

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

{

total = total + multi / i;

multi = multi
