The text passage contains a problem statement and a series of test cases for a solution to the problem. The problem is to find the average of a random sequence without using certain functions.
multiple_questions_with_answers

the passage includes multiple test cases, each of which implicitly contains a question (to verify the correctness of the `meanwhile` function) and an answer (the expected average value).
Given a text passage, determine:
    1. If it contains a mathematical question (including word problems or calculations)
    2. If an answer to that mathematical question is provided in the text

First, describe the content structure you found in 1-2 sentences.

Then provide your analysis in the following format:
TYPE: <one of the following values>
- NO_QUESTION
- SINGLE_QUESTION
- SINGLE_QUESTION_WITH_ANSWER
- MULTIPLE_QUESTIONS
- MULTIPLE_QUESTIONS_WITH_ANSWERS
