This year’s AMC 8 was more difficult than the last year’s AMC 8. Some hard problems were even AMC 10 level. For example, Problem 23 and Problem 24 on the 2017 AMC 8 are two typical AMC 10 hard problems.

Problem 23 is involved in detecting a sequence of four factors of 60 that forms an arithmetic progression with a common difference of 5.

Problem 24 is equivalent to finding the number of integers among the first 365 positive integers that are not divisible by 3, 4, or 5. We should use the principle of inclusion and exclusion (for 3 sets) to solve this problem.
