Aman hits a golf ball (0.2 kg) which accelerates at a rate of 20m/s^2. what amount of force acted on the ball?

Iwould say d but i am not 100% positive

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
