The choices aren't posting on here right for some reason so I figured it'd just be easier to screenshot it.

anonymous · Answer

they all say $f(1)=7$ so we can ignore that part

anonymous · Answer

and the next oneafter $7$  is $4$ 
so we have to see which one has $f(2)=4$

anonymous · Answer

$$f(2)=4=7-3$$ so pick the one that has  
$$f(n+1)=f(n)-3$$

anonymous · Answer

i can see how this can be confusing
do you need more of an explanation?

anonymous · Answer

Thank you so much! I was just totally lost with that but you explained it perfectly.

anonymous · Answer

I'm doing an end-of-the-module quiz and I left it to do until the end of my course so I was a little rusty on sequences. You explained it very well :)

anonymous · Answer

ok then i will not go further
i think in the problem you have to get then when you are given the sequence 
$$7,4,1,-2$$
it means 
$$f(1)=7,f(2)=4,f(3)=1,f(4)=-2$$
