In other words,

Therefore, the first choice is correct.
The graph of the inequality is also attached below.
Answer:
9, 10, 11, 12, and 13
Step-by-step explanation:
The first term is determined when n=1, therefore a(1)=1+8=9
The second term is determined when n=2, therefore a(2)=2+8=10
The third term is determined when n=3, therefore a(3)=3+8=11
The fourth term is determined when n=4, therefore a(4)=4+8=12
The fifth term is determined when n=5, therefore a(5)=5+8=13
