问题 1 , 2/3 , 5/9 , ( ) , 7/15 , 4/9

选项 A.1/2 B.3/4 C.2/13 D.3/7

答案 A

解析可以化成: 3/3,4/6,5/9,(),7/15,8/18 其中分子是3,4,5,(),7,8 分母是3,6,9,(),15,18 分子是个公差为1的递增数列所以分子数列的()填5+1=6 分母是个公差为3的递增数列所以分母数列的()填9+3=12 所以答案应该是6/12=1/2

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
