No, it is not A.

Notice that the distance between every two adjacent terms INCREASES with "n".

So, it can not be NEITHER A nor B.

Next, you can to choose between C and D by making some trials.

There is NOTHING DIFFICULT in it . . .

No, it's NOT A.
I see you got CAUGHT thinking that itw's choice A. because choice A. works for the 1st 2 terms.
Unfortunately though, choice A. doesn't work for the other 2 terms!
