If you have ever had to deal with arrays, to access a particular index in an array, you can simply use the square bracket notation like so: array[1]. This will return the the item of the array at position 1. Well, how do you access a particular index in a list? You can use .ElementAt.

var numbers = new[] { 2, 4, 6, 8, 10 };

int number = numbers.ElementAt(3);

//output: 8
