Getting weird average of numbers between two numbers that the user entered

I just want only the average. I already did the sum.

import java.util.Scanner;

public class inbetweennumber {
    public static void main(String args []){
        Scanner input = new Scanner(System.in);
        System.out.println("Enter the 1st number");
        int num1 = input.nextInt();
        System.out.println("Enter the 2nd number");
        int num2 = input.nextInt();
        int sum = 0;
        double avg;

        for (int i = num1 + 1; i < num2; i++) {
            sum += i;
        }
        System.out.println("Sum: " + sum);
        avg = sum / num2;
        System.out.println("Average: " + avg);
    }
    
}

This not working for me. Example session:

Enter the 1st number
5
Enter the 2nd number
10
Sum: 30
Average: 3.0

The sum is correct: 6 + 7 + 8 + 9 = 30. The average should be 7.5, but comes out as 3.0.

your average calculator is wrong. Please change it look like this;

avg =(double) sum / (num2-num1-1);
