Question

WAP in java to Display the sum of the series, where s = 1/3 + 2/5 + 3/6 + ……… 9/12 by any method. Please give the answer in Scanner mode and with messages if you can. Thank you

Answer 1

Answer:

Explanation:

Input : 3

Output : 9

Explanation: So here the tern of the sequence upto n = 3 are:  

            1, 3, 5 And hence the required sum is = 1 + 3 + 5 = 9

Input : 6

Output : 36

// CPP program to find summation of series  

#include <bits/stdc++.h>  

using namespace std;  

 

int summingSeries(long n)  

{  

   // use of loop to calculate  

   // sum of each term  

   int S = 0;  

   for (int i = 1; i <= n; i++)  

       S += i * i - (i - 1) * (i - 1);  

     

   return S;  

}  

 

// Driver Code  

int main()  

{  

   int n = 100;  

   cout << "The sum of n term is: "

       << summingSeries(n) << endl;  

   return 0;  

}
