A worker is paid $0.10 on the first day, $0.30 on the second day, $0.90 on the third day, $2.70 on the fourth day, and so on.
Notice that the pattern of getting wages is 3 times of the previous day.
Like the wages for the first day= 0.10
Second day = 0.10*3 = 0.30
Third day = 0.30 *3 = 0.90 And so on.
Hence the wages represent a geometric sequence where
first term: a = 0.10 and common ratio: r = 3.
And we need to find the total does the worker earn after working 14 days:.
Formula to find the sum of nth term a geometric sequence is:
=
=
=
=
= 239148.4
So, he will earn $239148.40 fter 14 days.
Hope this helps you.

Your initial instinct would be to solve this problem with this solution. 34 x 57 = 1,938 petals.
However, the word estimate is present; therefore, we have to consider that we need to get the approximate number and not the exact number of petals.
There is a general rule regarding estimation or approximation. You have to round it to the nearest place you have based on. In this problem we round it off to the nearest tens place.
If the number is below 5, you round it down: 34 is rounded down to 30 petals.
If the number is above 5, you round it up: 57 is rounded up to 60 sunflowers.
Thus, your equation would be : 30 x 60 = 1,800 petals (best estimate)
