Math patterns

It's derived from the Fibonacci sequence. The explicit formula for the nth term
in the Fibonacci sequence can be found here:

1+1=2
2+1+2=5
5+1+2+5=13
13+1+2+5+13=34
etc.

Thanks, I would have never gotten that. Seems pretty tough for a 5th grade question.

Thank you for your post. I'm sad to report that I couldn't begin to understand it. So glad that there are people in the world that can though. Appreciate your help.

Oh, sorry. I didn't know it was a fifth grade question.

Yeah, I guess my answer would not have done you much good.
