Write three arithmetic and three geometric means between 4 and 324

  • math - ,

    So in each case you would have 5 terms

    AS:
    a = 4, t(5) = a+4d = 324
    4 + 4d = 324
    4d = 320,
    d = 80

    the three missing terms are 84 , 164, 244

    GS:
    a = 4, t(5) = ar^4 = 324
    r^4 = 81
    r = ± 3
    if r = 3, the three missing terms would be
    12, 36, 108
    if r = -3 , the three missing terms would be
    -12 , +36, -108
