答案与解析

1.答案:

解析:

2.答案:

解析:

原数列为三级做差数列。

数列中,后项减去前项可得-1、9、3、13,再次后项减去前项可得10、-6、10,为周期数列,则下一项为-6,因此上一层的下一项为7,原数列的未知项为34。故正确答案为B。

3.答案:

解析:

原数列可化为11/3、7/3、3/3、( )、﹣5/3,分母均为3,分子11、7、3、(﹣1)、﹣5是公差为﹣4的等差数列,则原数列未知项为﹣1/3,故正确答案为B。

4.答案:

解析:

原数列本身为质数数列的反向排列,括号内应该为19,故选择C选项。

5.答案:

解析:

>> >子数列一:0123、 > 4、(> 5 > > (等差数列)

>> >子数列二:1234、 > 5、(> 6 > > (等差数列)

>> >子数列三:2345、 > 6、(> 7 > > (等差数列)

即0=0*1*2;6=1*2*3;24=2*3*4……,故正确答案为5*6*7=210,选择B选项。
