Answer:
The required formula is:
Step-by-step explanation:
The total number of squares of the the first term = 4
The total number of squares of the the second term = 7
The total number of squares of the the third term = 10
so,
Finding the common difference d
As the common difference 'd' is same, it means the sequence is in arithmetic.
So
If the initial term of an arithmetic progression is and the common difference of successive members is d, then the nth term of the sequence is given by:
Therefore, the required formula is:
Graph D, because no x-value repeats and it passes the vertical line test.

22. Distributive Property
I think you have to subtract 60% and 80% which you get 20%
