Answer:
1) 5000/8 = 625
r = 625^(1/4) = 5
8, 40, 200, 1,000, 5,000
2) 648/3 = 216
r = 216^(1/3) = 6
3, 18, 108, 648
3) 1,701/7 = 243
r = 243^(1/5) = 3
7, 21, 63, 189, 567, 1,701
4) 648/8 = 81
r = 81^(1/4) = 3
8, 24, 72, 216, 648
5) 2,243/2 = 1,121.5
r = 1,121.5^(1/5)
2, 8.147, 33.186, 135.179, 550.6421, 2,243
