    Multiply by - 4/5

    Step-by-step explanation:

    To find the sequence, take the second term and divide by the first

    32/5 : - 8

    32/5 * 1/-8 = - 4/5

    Check with the 3 divided by the second

    -128/25 : 32/5

    -128/25 * 5/32 = 5/25 * - 128/32 = 1/5 * -4 = - 4/5

    We are multiplying by - 4/5
