What is true about the variable x when the variable n is a negative number?

Before anybody (including you) can try to answer this, you need to know

how 'x' and 'n' are related. That information typically takes the form of an

equation that has both 'x' and 'n' in it, and it's quite likely that the equation

is right there next to the part of the question that you DID copy and post.
