Answer:
true.
Step-by-step explanation:
In mathematical, literary, or musical terms, it is true that a sequence implies repetition. In broad terms, a sequence is a collection of elements that are repeated in a given format.
Taking the example of music, a sequence would be a series of sounds that conform what is called a passage that is repeated successively, more often than not (although in contemporary music this is not always the case), at a different pitch.
