          In the first row,




          The number in the middle circle is the sum of the numbers in the left and right circles in the same positions.




          In the second row,




          The number in the middle circle is the difference between the numbers in the left and right circles in the same positions. It does not matter which is subtracting from which, it is the absolute difference.

          • Interestingly, if the 5 in the bottom right circle is changed to a 3 then the pattern which has only subtly changed would be more easily stated, because the upper and lower rows would have the same pattern. Of course, this would change the value of the "?"

          If we number the circles as follow:

          First row A B C

          Second row D E F

          On the first row we get for each corresponding sector B(n) = A(n) + C(n)

          namely: 5 = 2 + 3, 7 = 6 + 1, etc.

          On the second row the rule seems to change to alternating D(n) - E(n) = F(n)

          and in the next segment D(n+1) + E(n+1) = F(n+1)

          Starting from top left we get 7 - 1 = 6, 1 + 4 = 5, 8 - 6 = 2, 2 + ? = 9

          Which leads us to ? = 7
