It is asking you to continue the pattern which in this case means that the top term is being multiplied by three while the bottom term is being divided by 2.

I am NO expert at this, but I think I found the original binomial,

and putting that into WolframAlpha gives the answer:

Someone else can probably explain this the *right* way !! Haha
