So first you want to convert both to have the same denominator.
5 1/2 - 3 3/4
To:
5 2/4 - 3 3/4
Now, to make it easier for me, I would convert both to an improper fraction.
5 2/4 -> 22/4
3 3/4 -> 15/4
So now you can just do,
22/4 - 15/4,
which is just 7/4.
This in mixed number form is 1 3/4.
I believe your answer is going to be increasing linear. If it's doubling constantly then it's increasing so that takes out 2 options. And since it's constant, it isn't exponential, therefore you only have increasing linear left.
I hope I was able to help. Best of luck.
