问题 1/140,1/80,1/45,1/25,( ) A.1/15 B.1/10 C.1/7 D.4/55
选项
答案 D
解析 观察数列,本题全部为分数,并且分子都为1,观察分母变化规律: 140÷2+10=80 80÷2+5=45 45÷2+2.5=25 所以答案分母为:25÷2+1.25=55/4 故最后答案为4/55,应该选择D。

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).
