this is geometry? so there's a figure?

anonymous · Answer

It has no picture with it. That's the question.

I just started Geometry and this is what they ask me? 
I think it has to do with patterns.

Hints:
Note that the letters alternate in case.
Check the difference of the numeric portion of successive terms.

Yes, they're correct. I think it's a pattern.

Pattern for numbers: 11?
