猜的啊
a b c是三个连续偶数,且三个的平均数是8
求a b c 20 四个数的中位数?
答案是9

选D

平均(算术平均值)的连续三次甚至整数a,b和c是8。什么是平均的,乙、丙、20岁吗?

a、b、c三个数的算术平均值是8,那么a, b, c, 20四个数的平均值是多少?
答案应该是D

The average (arithmetic mean) of three consecutive even integers a, b, and c is 8. What is the median of a, b, c, and 20 ?
三个连续的数abc的平均值是8,三个数的中间数是什么?
后面的and 20不知道是什么意思(还有20)

三个连续整数 a, b 和 c 的算术平均值是8。
a, b, c, 20四个数的平均值是多少?
答案是11

a.b.c 的平均值是8 求a.b.c和20 四个数的中位数
