how to find the four geometric means between 5 and 1215

  • math -

    sqroot(5*1215)=sqroot(6075)=77.9423

  • math -

    so you would have
    5 m n o p 1215

    that is..
    a = 5 and t(6) = ar^5 = 1215
    5r^5 = 1215
    r^5 = 243
    r = 3

    so the 6 terms would be
    5 15 45 135 405 1215
