New term has come,and the teacher has given the numbers new seats.The numbers have found their seats in the front.Can you find out who will take the last seat?Use your head!新學(xué)期開始了，老師給數(shù)字寶寶安排了新座位。前面的數(shù)字寶寶們已經(jīng)坐好了。請(qǐng)根據(jù)它們位子的規(guī)律，你能找出哪個(gè)數(shù)字寶寶應(yīng)該坐最后一個(gè)座位嗎？動(dòng)動(dòng)腦筋哦！

每組座位中，橫排前兩個(gè)數(shù)字的乘積等于豎排第二個(gè)，橫排后兩個(gè)數(shù)字的乘積等于豎排第三個(gè)。按照這個(gè)規(guī)律，在第四組座位中，3×7=21,8×7=56,所以空出的座位是留給56的。
