Step-by-step explanation:
First, divide the 12 cupcakes by 4 1/2. This will find the rate of change or slope of the equation. The answer of 12 divided by 4 1/2 is 8/3. That would make A the correct choice for this problem.
You can use the arithmetic sequence equation. This will tell you the number of seats in the last row
An = A1+ (n-1)d
<span>An = 4+(24-1)5 </span>
<span>An = 4 + (23)(5) </span>
<span>An = 4 + 115 </span>
<span>An = 119 </span>
Then, you take that answer and plug it to this equation: <span>Sn = n(a1 + an)/2 </span>
<span>
Sn = 24(4+119)/2 </span>
<span>Sn = 24(123) /2 </span>
<span>Sn = 1476 </span>
