Write a program to find the average of all numbers till a given number.

Input (Integer) Output (Integer)
7 (1 + 2 + 3 + 4 + 5 + 6 + 7) / 7 = 4
15 (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15) / 15 = 8

``` class Average {     public static void main(String s[])    {        System.out.println("Average of numbers till 5 is " + averageOfNumbers(5));    }     public static int averageOfNumbers(int input)     {         int output = 0; ```
```         return output;     } } ```

### User comments below.All of them might not be correct.

for(int i = 1; i <= input; i++)
{
output += i;
}
output /= input;

for(int i=1;i<= input ;i++){
output +=i;
}
output /=input ;

Step 1: calculate sum of all the numbers starting from 1 to the given number.This can be achieved by using the for loop by iterating from 1 to the given number and adding the values cumulatively for every iteration
Step 2: Divide the sum obtained from Step1 with given number to get the average

Here we can write For loop, Initializing loop control variable i to 1 and the condition Which is less than equal to input.. By satisfying this condition The output may be printed by incrementing the initial varible upto the given input and stores in output,  To get the average of given input, The stores output can be divided by the given input.

single step without the concept of loops is
output=(input+1)/2;// basics of average is 1+2+3+.......+n=n(n+1)/2 average=n(n+1)/2/n=(n+1)/2;
return output;

here we need to iterate the the from 1 to till the given num...to iterate we need to use the loops...to find avg first we need to find the sum of the given range..so here we need to take an varaible and must be iniatilized with the 0...while iterating every time we need to add the loop control to the sum...once we complete thr iteration..than we need to divide this sum by the given input than we will get the avg
