    This does not have a common ratio

    Step-by-step explanation:

    To find the common ratio, take the second term and divide by the first term

    15 / - 3 = - 5

    The common ratio is - 5

    Verify by taking the third term and divide by the second term

    -45/15 = - 3

    These numbers are not the same, so there is not a common ratio
