Answer:
67
Step-by-step explanation:
Use the average formula: average = sum of elements / number of elements
Let x represent the score of their last game, and plug in the average, other scores, and number of elements into the equation:
56 = (48 + 57 + 52 + x) / 4
Simplify:
56 = (157 + x) / 4
Solve for x, by first multiplying each side by 4:
224 = 157 + x
Subtract 157 from both sides:
67 = x
So, the score of their last game was 67.

You need to use the addition formula when the last term is not given. Mind you, you could find it, but it is just as easy to get the answer without it.

a1 = 2
d = 3
n = 36
Formula
Sum = n(a1 + (n - 1)* d)/2
Solution
Sum = 36(2 + (36 - 1)*3 )/2 Combine the brackets
Sum = 36 (2 + 35*3 )/2
Sum = 36(2 + 105) /2 Combine the brackets
Sum = 36 * 107/2
Sum = 3852 /2
Sum = 1926
Answer
1926

40/8 is 5. You can check this by multiplying 8 and 5 and seeing if it equals 40. Also, if you look at 40/8 as a fraction you can simplify it. 40/8=20/4=10/2=5/1=5
There is no other answer. It is only 24
