First, let's evaluate how many people are leaving the town that year, it will be 10% of 24000
[tex]10\%\text{ of 24000 = 2400}[/tex]
2400 people are leaving but 1200 are moving to the town, then, in fact, the population will reduce in 1200, the next year population will be
[tex]2400-1200=22800[/tex]
Take 10%, subtract 1200 (moving to the town), we will get
[tex]1080[/tex]
If we continue that process, we will get
[tex]\begin{gathered} 972 \\ 874.8 \\ \end{gathered}[/tex]
Then, we can see that the number of people "leaving" the town is going down, then, the tendency is to stabilize.

a) Do the same logic to fill the table
c) The formula will be something like
[tex]f(n) = f(n-1)\cdot 0.9 + 1200[/tex]

You're expecting a exponential decrease
