Question

3

Answer 1

first 5, then \(5\times 2\) then \(5\times 2^2\) etc, since you only want the amount in august, and not the total, it represents a geometric SEQUENCE (series would be if you added them)

Answer 2

frankly i don't understand what 'how many total cans are on the bottom 14 rows' means

Answer 3

if there are 32 cans on the bottom row, then there are 30 cans on the one above it, 28 on the one above that, and so on. this would be an arithmetic sequence
\[32, 30, 28, 26, ...\]

Answer 4

does this mean 12% a year every year?

Answer 5

if so, the answer is
\[8\times (1.12)^6\] (in millions of course )

Answer 6

since you are only asked for the number at the end, it is a geometric sequence

Answer 7

looks like
\[8,8\times 1.12, 8\times 1.12^2,8\times 1.12^3, ...\]
