1. 9/3
This is because 3 = 3/1, and if multiplied by 3/3 becomes 9/3.
2. 4/2
See above, this time we multiply by 2/2
3. 20/4
See above, this time we multiply by 4/4
4. 5/5

Answer:
There are 5 boxes on the tenth row.
Step-by-step explanation:
We are given the following information in the question:
Each row of tissues has 2 fewer boxes than the row below.
The first row has 23 boxes of tissues.
23, 21, 19, 17,...
a) Let f(x) be the function that represent the arithmetic sequence.
Then,
, where x is the number of boxes in previous rows.
b) Comparing the given sequence to an arithmetic progression, we have
First term,a = 10
Common difference,d = -2

Thus, there are 5 boxes on the tenth row.
