ответ:6

Пошаговое объяснение:Смысл заполнения магического квадрата состоит в следующем: сумма чисел по вертикали горизонтали и двум диагоналям должна быть одна и также.  

Идея решения следующая (покажу на первом квадрате:  

1. По диагонали сумма 15  

значит в нижнем ряду тоже 15 т. е. в пустой квадрат заносим 15-9-2=4, значит слева между 8 и 4 заносим: 15-8-4=3.  

Второй горизонтальный ряд: 15-3-5=7.  

Вертикальный средний: 15-9-5=1  

Ну и последний правый верхний замыкает: 15-8-1=6 и проверяем: 15-7-2=6
