✅ Array Problem - the variable "i" here appears to never change?

int[] numbers = new int[5];

for (int i = 0;i < numbers.Length; i++)
{
    Console.WriteLine($"Please enter a number to fill index: {numbers[i]}");
    int userInput = Convert.ToInt32(Console.ReadLine());
    numbers[i] = userInput;
}

    numbers[i] = userInput;
