How many odd integers are greater than the integer x and
less than the integer y ?
(1) There are 12 even integers greater than x and less than y.
(2) There are 24 integers greater than x and less than y.
--------------------------------------------------------------------------------------------------------------------------------------------------------【答案】B
【思路】
(1) 不知道有几个数是介於x,y. 有可能奇数比偶数多1或少1
(2) 有一半是奇数
answer: B
我想请问根据B答案的解释 他说24个整数 有一半为奇数
但是题目好像也没指明 这24个数是不是CONSECUTIVE INTEGERS
请问这样怎麽判断
