例句:
1, 3, 5, 7, 9 都是奇数。(1, 3, 5, 7, and 9 are all odd numbers.)
我猜测奇数在这个序列中比偶数多出一个。(I guessed that there is one more odd number than even number in this sequence.)
我们可以通过把奇数和偶数的平均数相减来得到奇数的平均数。(We can find the average of the odd numbers by subtracting the average of the even numbers from the average of all numbers.)
