36. Adams's Magic Hexagon. In 1957, Clifford W. Adams discovered a magic hexagon in which the sum of the numbers in any "row" is 38. Fill in the empty cells of the partially completed hexagon shown, using the whole numbers 6, 7, . . ., 15, to re-create Adams's discovery. When completed, each cell will contain one of the numbers 1, 2, . . . , 19. 238 18 + 17 +3 = 38 3+ 19 + 16 = 38 1. 18 16 19 17 42.
