The sum problem of sequence an = 3 / (2n-11) n belongs to positive integer, and the sum of the first n terms of sequence {an} is Sn, so what is the minimum value of n with Sn > 0 Summation of sequence An = 3 / (2n-11) n is a positive integer, and the sum of the first n terms of the sequence {an} is Sn, so what is the minimum value of n with Sn > 0? In addition to one written out, other clever solutions

In addition to one written out, other clever solutions

From the denominator 2n-11, we can see that when n = 5, it is - 3, when n = 6, it is 3, and the sum of their values is 0;
Similarly, the sum of n = 4 and N = 7 is 0; ···; the sum of n = 1 and N = 10 is 0; therefore, if Sn > 0, then the minimum n is 11
