    I was doing it with a different way, like
    16th: 6(1.2)
    17th:6(1.2)^2 and so on... so that's why I am having trouble with 5

    first part

    75 minutes to cover 15 Km

    so the pace is 5 minutes every km
    so time increases by 20%

    5 x 1.2 (minutes) for the the 16th km
    (5 x 1.2)/60 (hours) for the the 16th km

    and so on
