Find the pattern

$1$

$1$ , $2$

$1$ , $3$ , $2$

$4$ , $1$ , $3$ , $2$

$5$ , $4$ , $1$ , $3$ , $2$

$5$ , $4$ , $1$ , $6$ , $3$ , $2$

$5$ , $4$ , $1$ , $7$ , $6$ , $3$ , $2$

$8$ , $5$ , $4$ , $1$ , $7$ , $6$ , $3$ , $2$

$8$ , $5$ , $4$ , $9$ , $1$ , $7$ , $6$ , $3$ , $2$

$8$ , $5$ , $4$ , $9$ , $1$ , $7$ , $6$ , $10$ , $3$ , $2$

If we continue the pattern above, in which position should $11$ be placed?

For example, if you think the next sequence should be

$8$ , $5$ , $4$ , $9$ , $1$ , $7$ , $6$ , $\boxed {11}$ , $10$ , $3$ , $2$

then your answer should be $8th$ .
