Question

Write a program to find the series upto n terms: 0,3,8...

Answer 1

Answer:

import java.util.*;

public class Series

{

public static void main(String args[ ])

{

Scanner in=new Scanner (System. in);

int a,c,n;

System.out.println("Enter the value of n");

n=in.nextInt();

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

{

c=Math.pow(a,2)-1;

System.out.println("The series is ="+c);

}

}

}

Explanation:

In the given series it is the subtractive result of 1 from the square of the numbers.

Such that,

(1×1)-1

=1-1

=0

(2×2)-1

=4-1

=3

(3×3)-1

=9-1

=8

And vice versa.
