Working on patterns. There is a diagram. Its a rectangle with the numbers 10, 16, 23 in each corner. Inside the rectangle is a circle and inside the circle are the numbers 9, 12, 24. The directions say to place the numbers 8 to 26 either inside or outside the circle according to the pattern shown. Please help

My son got the same question but I do not know how to solve it. Please help? Thanks
