        int[] input = {16,1,2,0,4,2,7,1,2,14};
        
        int avg = (int)Math.Ceiling(input.Sum() / input.Length);
        int min_pos = 2147483647;
        
        for (int i = input.Min(); i <= avg; i++)
        {
            int pos = 0;
            
            foreach (int num in input)
            {
                pos += Math.Abs(num - i);

        }
        
        int result = min_pos;
        Console.WriteLine(result);

What's the full error message? You've just shown the first bit.

I'm guessing you probably wanted to do a floating-point division there? You're currently dividing an int by an int, which gives you an int. Calling Ceiling on an int doesn't make any sense (int)Math.Ceiling((double)input.Sum() / input.Length)
