Exit Slip:Suppose a balloon is filled with 5000 of helium. It then loses one fourth of its helium each day.
a. Write the geometric sequence that shows the amount of helium in the balloon at the start of each day for five days.
b. What is the common ratio of the sequence?c. How much helium will be left in the balloon at
the start of the tenth day.
