General term of sequence A1 = 2, an = [a (n-1) + 1] * [10000 + 10000a (n-1)] / [10000 + 10000a (n-2] to find the general term formula, this, should not be solved... No way to start

We can eliminate 10000 and transform it into an / [1 + a (n-1)] = [a (n-1) + 1] / [1 + a (n-2)]. There is no rule in this form. If we change a (n-1) + 1 into a (n-1), we can solve it. At the same time, the problem can not be solved without A2 iteration
