  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
