Answer:
Peter missed five questions.
Step-by-step explanation:
Since the test has twenty-five questions, and Peter got 80% correct...
80/100 = __/25 <--What number is the numerator?
Well, to get from 100 to 25, you have to divide by 4. 100/4 = 25.
Now, what is 80/4? If you do the math, you should get 20.
25 (Total Questions) - 20 (Questions Correctly Answered) = 5 (Questions Incorrectly Answered)

Not sure what you are asking but if you are looking for the next 3 numbers then multiply 5 by 1.5, 7.5 by 1.5, and 11.25 by 1.5
5 * 1.5 = 7.5
7.5 * 1.5 = 11.25
11.25 * 1.5 = 16.875
16.875 * 1.5 = 25.3125
25.3125 * 1.5 = 37.96875
37.96875 * 1.5 = 56.953125
