別笑我嘛... 我又來問笨問題了... :-$
Q27:
In a certain sequence of 8 numbers, each number after the first is 1 more than the previous number. If the first number is –5, how many of the numbers in the sequence are positive?
A. None
B. One
C. Two
D. Three
E. Four
我的作法:
就是-5 -4 -3 -2 -1 0 1 2 八個數字囉
我選C耶 因為0不是可正可負嗎?!
不好意思 數學很差 一直來煩大家
