4.75 is the answer list from least to greatest find the number in the middle
Answer:
y=4x-1
Step-by-step explanation:
The middle section is n(n+1)
The top row is n+2
The bottom row is 2n+1
So the rule for the total number of tiles will be the sum of the above rules...
s(n)=n(n+1)+n+2+2n+1
s(n)=n^2+n+n+2+2n+1
s(n)=n^2+4n+3
The answer is -83.7418
Rounded to: -83.74
