Yeah, but how long did it take you to figure that out? Took me about 5 seconds. It’s a good stumper, I think.

I didn’t use a stopwatch but it took me less than 10 seconds. At first I read them, thought of a pattern then realizing there wasn’t one compared the two next to it and realized the issue.

87. But it took me longer than 20 seconds to figure it out. Others may be faster.

Here is a hint: It all depends on your perspective.
