Question

Write a program to find the following series upto n terms:
-1,6,25....

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,3)-2;

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

}

}

}

Explanation:

In the given series it is the subtractive result of 2 from the cube of the numbers.

Such that,

(1×1×1)-2

=1-2

=-1

(2×2×2)-2

=8-2

=6

(3×3×3)-2

=27-2

=25

And vice versa.
