143乘以52减去129乘以43加上143乘以77巧算方法
我有更好的答案
143 * 52 - 129 * 43 + 143 * 77= 143 * (52 + 77) - 129 * 43= 143 * 129 - 129 * 43= 129 * (143 - 43)= 129 * 100= 12900

d c d a 第一第4道他讲的很对拉,第三道是 0^2+12^2-14^2+16^2-18^2+1..第2道我也没做出来,帮你把答案找来了~把每一个都除以3,看余数 9÷3余数为0； 1÷3余数为1； 4÷3余数为1； 3÷3余数为0； 40÷3余数为1； 由两个余数为1的数,后都减1÷前都有一个倍数,即：n=(4-1)÷1=3；则有（x-1)÷40=3(x为第六个数) 即为：x=40×3+1=121.
第一题选D：17，两个数之间差的5的倍数，一次是1倍、2倍、3倍、4倍。第四题选A27，数之间差依次是2的平方、3的平方、4的平方、5的平方。才疏学浅，其他的没做出来~~~
