题目

求数学定义翻译（有关arithmetic mean和geometric mean的）
如题,看到arithmetic mean 的英文定义,但不知道中文是什么意思,求翻译.原句如下：
if there is one term falling between two given terms of an arithmetic sequence, it's called arithmetic mean.
另外,还有对应的geometric mean的：
if there is one term falling between two given terms of an geometric sequence, it's called geometric mean.
请知道的人帮忙解答一下,谢谢!
灌水勿答,只会用翻译器的勿答.

答案

arithmetic mean的意思是算数平均数,或者等差中项
if there is one term falling between two given terms of an arithmetic sequence,it's called arithmetic mean.
如果某一个项落在一个算术序列的两个给定值之间,则称为算术平均数.
geometric mean解释为几何平均数,或者等比中项
if there is one term falling between two given terms of an geometric sequence,it's called geometric mean.
如果某一个项落在一个几何序列的两个给定值之间,则称为几何平均数.
