Determine whether the sequence converges or diverges. if it converges, give the limit: 72, 18. 9/2, 9/8,

 The sequence converges. The limit it converges to is 0.



The sequence is a geometric sequence with a = 72 and r = 1/4. Because 0 < r < 1, this means that the sequence gets smaller and smaller. The terms get closer to 0. They don't actually get there but the limiting value is 0. 

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
