What is the defining feature of a sequence that distinguishes it from a set?

Repetitions are not allowed but order matters

Repetitions are allowed and order matters (correct)

Repetitions are not allowed and order does not matter

Repetitions are allowed but order does not matter

What is an example of a valid sequence?

(3, 6, 9, 12, 15)
