Answer:
9.8
Step-by-step explanation:
a geometric sequence means we multiply the previous element by a certain factor to get the next element.
so, all we need to do is determine the factor used to go from one element in the list to the next.
a1 = 9
a2 = 88.2
a3 = 864.36
a4 = 8470.728
the simplest case is usually the case from a1 to a2.
a2 = a1×f
88.2 = 9×f
f = 88.2/9 = 9.8
we are finished here.
but we can control our result and verify with the other given elements.
88.2 × 9.8 = 864.36
and that is a3. fits.
864.36 × 9.8 = 8470.728
and that is a4.
so, all fits, we are correct.

Answer:
10 gallons of paint are needed
Step-by-step explanation:
If 1/5 gallon is 2/25 of the shed then 1 full gallon is 10/25 because 5 times 2 equals 10. So if 1 gallon is 10/25 then 2 gallons is 20/25 leaving 5/25 left of the first shed. 5 divided by 2 is 2.5, so therefore, it takes 2 gallons and 2.5/5 or 2.5 gallons simplified to paint one shed. Multiply 2.5 by 4 because you need to paint 4 sheds and that gives you 10.
