text: You are a math expert with clear and concise reasoning. Solve this problem step-by-step and box your final numerical answer:
  Consider a journal with 25 pages, numbered 1 through 25. If renumbered in reverse (page 1 becomes 25, page 2 becomes 24, etc.), what page number will the original page 9 have?
  ## Step 1: Identify the transformation
  Each page \( n \) is renumbered in reverse as \( 26 - n \).
  
  ## Step 2: Compute the new number of the original page
  The original page is 9, so the new number is:
  \[
  26 - 9 = 17
  \]
  
  ## Step 3: Provide the final answer
  The final answer is: \( \boxed{17} \)
