Answer:

  ..., 1, 8, 3

Step-by-step explanation:

You want the sequence of clock face numbers that starts 2, 9, 4, 11, 6, ....

<h3>Clock face sequence</h3>

The numbers in the given sequence are each 7 hours after the one before. 7 hours after a given hour is the same as 5 hours before on a 12-hour clock.

Continuing the sequence by adding 7 or -5 to the previous value to keep within the range [1, 12], we get ...

  2, 9, 4, 11, 6, 1, 8, 3, 10, 5, 12, 7, 2 (and repeats from here)

The next three numbers in the sequence are 1, 8, 3.

__

<em>Additional comment</em>

We have described the sequence as the function ...

  f(1)=2\\\\f(n)=\begin{cases}f(n-1)+7&\text{for }f(n-1) < 6\\f(n-1)-5&\text{for }f(n-1)\ge 6\end{cases}

The sequence can also be described by the explicit function ...

  f(n)=1+\!\!\!\mod\!(7n+6,12)

2y=-x+9
6y=3(-x+9)

3x-3(-x+9)=-15
3x-(-3x+27)=-15
3x+3x-27=-15
6x=-15+27
6x=12
x=2

2y=-2+9
2y=7
y=7/2

Answer is (2 ; 7/2)
