I can't do the two circles, but here...

Seat A/First Circle:
0,1,2,3,4,5,6,7,8,9
Set B/ Second Circle:
2,4,6,8,12,14,16
At the middle: 
2,4,6,8   

Seat A and  are joint sets. Did you understand?/ If no, I can give you a picture but it will take time. Here's some other examples:

First Circle:
s,i,l,e,n,t,n,g,h
Second Circle:
l,i,s,t,e,n,o,m
Middle Part:
s,i,l,e,n,t

Explanation;
The middle part is where you'll write the thing that are most likely the same from the two other circle.
