Fill in the missing numbers in this sequence:
15873×7=111111
15873×14=222222
15873×( )=333333
15 ( )×28=( )4
选项
答案
21,873,4444
解析
题干要求找出算式规律,在括号中填入正确的数字。根据观察,三个算式的第一个数都是15873,因此推断第四个算式的第一个数也为15873,得到第二个数字为873;四个算式的第二个数字分别为7,14,( ),28,容易发现后一个数字是7的倍数,得到括号中的数字为21,也是题目的第一个数字;四个算式的最终数值分别为11111,22222,33333,( ),容易发现括号中的为44444,也是题目的第三个数字。由此可知本题答案。
