Question

Write a program using loop to input numbers and print the sum of the following series s=1^2-3^2+5^2-7^2+9^2-11^2

Answer 1

Answer:

public class loop

{

public static void main(int n)

{

int i;int s=0;

for(i=1;i<=n;i=I+2)

{

if(i%2==0)

{

s=s+Math.pow(i,2);

}

else if(i%2!=0)

{

s=s-Math.pow(i,2);

}

}

}

}
