1. import java.util.*;
public class prog{
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
System.out.println("Enter the first no :");
int n = sc.nextInt();
System.out.println("Enter the second no :");
int num = sc.nextInt();
If(n<=num)
System.out.println(num+"Is greater than"+n+ "\n");
else
System.out.println(n+"Is greater than"+num+ "\n");
}
}

Explanation:
Answer:
Sorry I got syntax error in the first three questions(As I am just 10th grade and you are 12th), however I managed to get the fourth and fifth questions...
4th answer :
a1=11
d=11
n=10
an1=a1+(1-1)*d
an2=a1+(2-1)*d
an3=a1+(3-1)*d
an4=a1+(4-1)*d
an5=a1+(5-1)*d
an6=a1+(6-1)*d
an7=a1+(7-1)*d
an8=a1+(8-1)*d
an9=a1+(9-1)*d
an10=a1+(10-1)*d
print(an1)
print(an2)
print(an3)
print(an4)
print(an5)
print(an6)
print(an7)
print(an8)
print(an9)
print(an10)
5th Answer:
print('*')
print('* *')
print('* * *')
print('* * * *')
Outputs:
For 4th one
11
22
33
44
