Hi! I’m reviewing the solutions video for Arithmetic Progress Quiz #9 and the questions that the video provides solutions and explanations for do not match with the quiz I just took. I see some are there just out of order, but I don’t see the solution or discussion of #4 in the current quiz for example.
Share a screenshot of the question. Usually what’s discussed in the video is similar to that in the quiz, with minor adjustments (usually because the original question had some sort of flaw).
