9,3,1, 1/3, 1/9 ... i need three numbers in the pattern and i dont get it ...

The pattern is that you are dividing by 3.

Therefore, to work out the next three numbers, you need to divide the last number by 3.

So you'd do:

1/9 : 3 = 1/27

1/27 : 3 = 1/81

1/81 : 3 = 1/243

Therefore, the next three numbers are 1/27, 1/81, and 1/243.
