OK, you've got 3 fence posts arranged in one line, evenly spaced. Count the spaces between the posts.

you are correct

Now... what if you wanted a straight length containing 8 such spaces. How many posts would be necessary?

Yes. Now let's arrange the posts in a circular fashion, so that they enclose an area. How many posts are needed to have 12 spaces?

waoh there, let's try again, but with less spaces. OK, we want five spaces, circularly arranged. How many posts?

Because in a circle, two spaces merge into one.

1. Linear arrangement - 5 posts, 4 fences:

._._._._.

2. Circular arrangement - 8 posts, 8 fences:

  ._.
./   \.
|     |
.     .
 \._./

If you straightened the circle into a line, it would only have 7 gaps. That's because the "final post" in the line moves into the "first post" in the line, forming a "gap". Technically the straight line has a gap there too because you can circumnavigate the earth and come back to the first post.

True, however I believe one of the specifications was "evenly spaced", i.e. each space (or fence in my case) should be the same size.

Anonymous H replied with this 1 year ago, 5 hours later, 1 day after the original post[^] [v] #1,297,684

@previous (D)

If you made the posts equidistant around the globe, you would have the extra gap.

@previous (H)
That would be a circular arrangement though - the posts would would be on the perimeter of a great circle, wouldn't they?

well how about if we arrange 8 posts in a square formation, again the spacings are equal

Anonymous H replied with this 1 year ago, 2 hours later, 1 day after the original post[^] [v] #1,297,759

@1,297,693 (D)

Yes but I'm just making my point, the reason that the circle has the extra gap is that one pole is doing the same job as the straight line's two poles.

Anonymous G replied with this 1 year ago, 3 hours later, 1 day after the original post[^] [v] #1,297,805

@1,297,725 (boof)
Same as in the first question, but now with 4 sides. 2 spaces per side for a total of eight. No "extra gaps" or "merging of spaces" required. And our fence doesn't need to span the globe to demonstrate it. Nice.
