Question

Write a java program to generate the following series.
( 1 ) (1+2)2+ (1+2+3)3+(1+2+3+4)4+…….(1+2+3+……..+n)n
(2) SUM=(1)+(1+2)+(1+2+3)+(1+2+3+4)…n
(3) SUM=1/1!+2/2!+3/3!+4/4!+5/5!....n

Answer 1

import java.util.*;

public class n

{

static int sumOfSeries(int n)

{

int sum = 0;

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

for (int j = 1; j <= i; j++)

sum += j;

return sum;

}

public static void main String args [])

{

Scanner sc=new Scanner(System.in);

System.out.print("Please enter a number: ");

int n = sc.nextInt();

System.out.println(sumOfSeries(n));

sc.close();

}

}
