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:111111,222222,333333,( ),容易发现括号中的为444144,也是题目的第三个数字。由此可知本题答案。
