pls anwer fast​

Answer 1

Answer:

Program:-

import java.util.*;

public class Main

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

int ch,n;

System.out.println("Enter 1 for series 1:");

System.out.println("Enter 2 for series 2:");

System.out.println("Enter your choice");

ch=in.nextInt();

switch(ch)

{

case 1:

System.out.println("Enter the limit:");

int temp=3;

n=in.nextInt();

System.out.println("The series:");

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

{

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

temp=temp*2;

}

break;

case 2:

int t=1;

System.out.println("Enter the limit:");

n=in.nextInt();

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

{

System.out.print((t*t+1)+" ");

t++;

}

break;

default:

System.out.println("Wrong Choice");

}

in.close();

}

}

• The first photo is the output for 1st series.
• The second photo is the output for 2nd series.
• The third photo is the output for Invalid choice.

Also the case 2 you can also do like this:-

case 2:

int t=2,c=3;

System.out.println("Enter the limit:");

n=in.nextInt();

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

{

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

t=t+c;

c=c+2;

}

break;

This will also print the same series

2 5 10 17 26 37...
