Answer:
D: 9, 12, 15
Step-by-step explanation:
Okay, this one is a very simple and a not so hard question. I understand that teachers prefer kids to not lay out all the terms, but in this case, it won´t be horrible in doing so!
Were going to plug 6 into n, and that will make the formula look like,
F(6)=3(6)-9
18-9=9 so the 6th term is 9
Plug in 7=
F(7)=3(7)-9
21-9=12
The 7th term is 12
Plug in 8=
F(8)=3(8)-9
24-9=15 8th term is 15
That means terms 6, 7, and 8 are: 9, 12, 15
