Identify the error in the following code:
numbers ← [5, 10, 15] print(numbers[0])
AP Pseudocode list indices start at 1, not 0. Accessing index 0 will cause an error.

What is data abstraction?
Simplifying data by representing it in a general way.
How does AP Pseudocode index lists?
AP Pseudocode lists start at index 1.
Why is data abstraction useful?
It makes code neater, easier to edit, and simplifies element access.
How can strings be treated in relation to lists?
Strings are essentially ordered lists of characters.
Explain the concept of 'one-based' indexing.
Indexing starts at 1, not 0, for the first element in the list.
