You shouldn't even be relying on a website to pass your courses. This website can help you, but relying on this website alone for answers is going to bite you right in the butt sooner or later. Also, you can't blame the students here for your failures, the only person you have to blame for that is yourself.

I thought you all were lying at first but they were right. Do not listen to the people on the top of the page.
The first answer is:
C, because -2 x 2 is -4, 3 x 2 is 6 and so on.
The second answer is B, all you have to do is half the actual numbers, 2 = 1, 4 = 2.
The third answer is A, thats because 2 x 2.25 is 4.5. All the others are either two small or two big.
The fourth answer is C.
If you follow this, you’ll get 100% on your quick check.
