Answer 3

I need help

Answer 4

alrighty so do you know how to start these kinds of questions?

Answer 5

You already given f(1)
Find f(2)
replace all the n's in f(n+1)=f(n)-2 with 1

Answer 6

I said 1 because that part on the left side will be f(2) and the part on the right side will be f(1)-2

Answer 7

And you already know f(1) and are looking for f(2)

Answer 8

D ?

Answer 9

that is the correct answer

Answer 10

It is actually the only one that makes sense...lol.
Because f(1) is 10
the only f(1) that is 10 up there is the one that is option D
