successive？到底该怎么理解？

biandy

68. 说某女有6个成绩successive排，问最后1个成绩是多少？
1)前4个成绩average 8.5
2)最后2个成绩sum是12
我做来做去不知道，就随便蒙了个E
前4个成绩average8.5，那sum是34，就是说可能是10，9，8，7那么后两个应该是6，5？后来想想成绩可能也有0.5的。反正是没做出来。
[讨论] E。是否差了中值或某一个具体数值？

这里的successive到底该怎么理解？是连续的整数？还是象JJ所说只是连续的数，可以为小数？

就successive本身来讲，是“连续的”意思。

再问个蠢问题

向上的连续 和向下的连续 都叫 SUCCESSIVE 嘛？

！

GmatTest

"Successively" does not mean "continuously", it just mean " following in order ,following each other without interruption". When it says "six successiv score", it does not mean that the scores are consecutive, there are not in a sequence. It's just saying, when the person takes the first test, he has a score for the first one, then when he takes the second test, he has a score for the second test,... In the end, these six scores put together, the first one is for the first test, second one for the second test, and so on.

You should look up in a English dictionary, or check it in www.webster.com.
