Question

I just need only these more answers :D​

Answer 1

Answer:-

These are the required programs.

Question 23.

Series given:-

1 3 9 27

Logic:-

1=3^0

3=3¹

9=3²

27=3³

So, the series is in the form of 3ⁿ

This is the program.

class Series

{

public static void main(String args[])

{

int a=1;

for(int i=0;i<10;i++)

{

System.out.print(a+" ");

a=a*3;

}

}

}

Question 24.

import java.util.*;

class Price

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter the amount of purchase: ");

double a=sc.nextDouble();

double d;

if(a<=1000)

d=0;

else if(a<=5000)

d=5*a/100.0;

else if(a<=10000)

d=10*a/100.0;

else

d=15*a/100;

a=a-d;

System.out.println("Payable amount: "+a);

}

}
