Is it possible to get the geometric mean between a negative and a positive number? Is it possible to insert geometric means between a negative and a positive number?

  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
    
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

You cannot—it is impossible to calculate a geometric mean that includes negative numbers. To use negative numbers in a geometric mean calculation, you have to convert them to a proportion. For example, if you had an investment that returned -3%, you would use 1 - 0.03 = 0.97 as your value.

well its sort of possible, you need to use complex numbers when applying a root of even degree to a negative number, but im not sure if theres any point in applying GM to negative numbers
