问题 根据规律填出括号里的数字,1,5,7,37,(  )
选项 A.262 B.263 C.264 D.261
答案 D
解析 本题考查递推数列。从趋势上看数列变化越来越快,优先考虑乘积递推关系,可见7=15+2,37=57+2,接下来应是737+2,尾数是1,因此答案为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). Please check the Redis logs for details about the RDB error.
