Sue’s Sequence

Here’s a fun little sequence that Sue brought into the office the other day.

It goes from top to bottom. Can you guess what the next image in the sequence is? (Hint: don’t get too mathy with it)


  1. This was in some movie, but I can’t recall it right now. I feel like they were kids in the cafeteria and the “smart” kid was trying to figure it out, but he couldn’t and then the artistic girl came over and showed him how to do it. (This is going to bug me for a while…)

  2. That’s from a Simpson’s episode I think…

  3. I was trying to found out which episode and I ran into a whole guide to the Simpsons and math. I had no idea!

  4. That sounds about right. This is one of a whole genre of problems designed to frustrate math people. It looks and smells like our routine techniques might work, but is just meant to frustrate them. It’s good for us though.

  5. The episode is called “Lisa the Simpson.” (I can’t believe I knew that off the top of my head…)

  6. You’re right, I just googled it. That’s crazy! Never new you were such a hardcore Simpsons fan. Do you like Seinfeld? That’s what Sue and I are always quoting (although I’d be hard pressed to name a single title to any show?).

  7. Well, I still don’t get it. I believe I do know the answer but only because I watched the video and saw it revealed at the very end. But I still don’t get it. I even spent a good half hour googling on Lisa the Simpson and Professor Provolone’s Picto-Puzzle etc. Hold sh**. I just got it! You know what I like about this thread? The fact that nobody actually revealed the answer. Forces you to think.

  8. I love problems that make me say Holy sh**. Glad that was so much fun :)

  9. can someone just tell me???
    i think i’ve found that the answer is 6 but i don’t understand why

  10. scratch that got it.

  11. Sorry it took so long to get back. December was crazy for me. Yes, it is a double 6-one normal, one reflected.

  12. I want to add that it’s just very confusing, you have to know to first cover half of each and then it goes 1,2,3,4,5,6. So the last is a mirrored 6. It’s simple yet so difficult.

  13. It’s so simple yet so confusing. The pattern is 1,2,3,4,5,6. Two of these 6s together are mirrored. So each digit of the puzzle needs to be covered up to reveal the 1-5 pattern and then you know it’s numerical order. 6 is the missing number.
