Question
The tables show the cat population on two islands over several years. Describe mathematically, as precisely as you can, how the cat population on each island is chan year & 0 & 1 & 2 & 3 & 4 number of cats on Purr Island & 2 & 6 & 10 & 14 & 18 Describe mathematically, as precisely as you can, how the cat population is changing, ex, (added by 5 , subtracted by 2 , multiplied by 4 )

Answer
The cat population on Purr Island is increasing by 4 each year.
Explanation
To describe the cat population on Purr Island mathematically, we will analyze the data in the table provided. Observing the progression of the number of cats from Year 0 through Year 4, we can detect a common pattern. It is quite visible that the population of cats on Purr Island is incrementing each year. Given that Year 0 had 2 cats, and every consecutive year had an increment of a fixed number. The difference between each subsequent year’s population value (for example [6-2], [10-6], or [14-10]) seems to look constant, which altogether implies that the growth is linear.To confirm the pattern, let's calculate the differences between the populations of consecutive years:- From Year 0 to Year 1:
- From Year 1 to Year 2:
- From Year 2 to Year 3:
- From Year 3 to Year 4:
The difference is consistently 4 cats per year.
