1. It is not easy to see where one question ends and the next one begins.
You did not indicate which are your choices, so how can we evaluate your work

I will start you on the first one:
f(n)=4n+2
f(1) = 4(1) + 2 = 6
f(2) = 4(2) + 2 = 10
....
Now which choice shows this pattern?

-------
{5, 10, 15, 20,...}
,
f(1)=5
and
f(n)=f(n−1)+5
for
n>1

If this is the third question, you are correct

I will wait for you to separate and number the questions, I don't feel like spending a lot of time
guessing which is a question and which is the answer to a question

2. I assume that I know which lesson this is, Secondary Math unit 3 lesson 11..

1. {6, 10, 14, 18}
2. {3, 8, 13, 18}, f(1) = 3 and f(n)=f(n - 1) + 5 for n > 1
3. Her seat is the first number in the sequence, so f (1) = 8, which means that her seat number is 8. The set describing the sequence is then {8, 10, 12, 14}. The recursive formula is given as f (1) = 8 and f (n) = f (n - 1) + 2 for n > 1.
4.{3, 6, 9, 12} in which f(1) = 3 and f (n) = f(n - 1) +3 for n > 1
5. {7, 9, 11, 13} f(1) =7 and f(n) = f(n - 1) + 2 for n > 1
