👉 In mathematics, the concept of multiplicity refers to how many times a number appears in a sequence or series. For example, if you have a sequence of numbers {1, 2, 3, 4}, and you multiply each element by a constant factor k, the new sequence would be {k, 2k, 3k, 4k}. In this case, there are three times that number (k) appears in the original sequence.
