数列{an}={13,26,39,412,515,618,721,824,…}称为Smarandache 3n数字数列,该数列中的每一个数都可以分成两部分,使得第2部分是第1部分的3倍.利用初等方法研究了Smarandache 3n数字数列的渐近性质,给出一个有趣的渐近公式.
The sequences {an}={13,26,39,412,515,618,721,824,…} is called the Smarandache 3n-digital sequence.That is,the numbers that can be partitioned into two groups such that the second is three times bigger than the first.The main purpose of this paper is using the elementary method to study the asymptotic properties of the Smarandache 3n-digital sequence,and give an interesting asymptotic formula.
