Task 1064: development task in emrekuruu/math-openenv, an RL environment on the Hugging Face Hub. Let $a {10} = 10$, and for each positive integer $n 10$ let $a n = 100a {n - 1} + n$. Find the least positive $n 10$ such that $a n$ is a multiple of $99$.

The task

Let $a_{10} = 10$, and for each positive integer $n >10$ let $a_n = 100a_{n - 1} + n$. Find the least positive $n > 10$ such that $a_n$ is a multiple of $99$.
