Question
The question is not homework.  I have been out of school over 35 years and I am re-learning math/algebra on my own.  I was just needing some assistance.  Thank you.

There are n+1 equal spaces between the posts, so the distance between any two posts will be
d/(n+1)

Draw a few pictures to see why

Let "p" represent a post

If n=3

p  p  p  p  p

4 spaces

If n=7

p  p  p  p  p  p  p  p  p

8 spaces

there's a space in front of each post except the last one , so n+1 spaces
