Question 9 (Multiple Choice Worth 1 points)

[2.05]Braden improves his score with each practice quiz he takes. The number of incorrect answers can be represented by the expression 20 - 5n where n represents the number of practice quizzes he has taken. How many answers will he get incorrect after taking 3 practice quizzes?

Answer 1

Question 11 is easy since this is a multiple choice question. Just do the stated operation with the first number and see which choice it works for. Then verify it through the rest of the sequence to make sure it is correct.
For example: The first choice is to subtract 12 from the previous number so \(324-12=312\). Is 312 the next number in the sequence? No. So go on to the next choice.
