I know some of you who read this blog also read 360 but the sequence posted there today was too good to not pass along:

**Puzzle: Identify the next term in the sequence**

**1, 11, 21, 1211, 111221, 312211, 13112221, . . .**

[HINT: Read the digits aloud. The sequence is aural/visual and not numeric.]

I’ll post the answer tomorrow or the next day.

That was fun…Are we allowed to post the answer?

First come, first serve, but make sure you explain it.

Clever.

It’s shorthand/IMspeak for describing the previous term…

Start with “one” = 1

Then describe it: “one one” = 11

Then describe that: “two one(s)” = 21

Then describe that: “one two, one one” = 1211

and so on.

You can change it any way you like, just start with a new first number.

Much simpler than I would have explained it…but how I would have explained it would have been for my amusement alone…

1211–>”one one, one two, two one”=111221

111221–>”three one, two two, one one”=312211

…

13112221–>”one one, one three, two one, three two, one one”=1113213211!

And so on and so forth…
