Ответ: 21400 (а).
Решение:
В трех нижних клетках стоят числа 7200, 4500, 5200. Еслс мы сложим соседние из них, то получится:
7200 + 4500 = 11700.
4500 + 5200 = 9700.
Два полученных результата сложим и получим ответ:
11700 + 9700 = 21400.
Как мы видим, здесь работало одно частое правило: если сложить любые два нижних соседних числа, то получится верхнее над ними.
