3 / 1 = 3
9 / 3 = 3
27 / 9 = 3

so... r = 3

It's 3. 1*3=3, then 3*3 = 9 and 9*3 = 27. The next number in the sequence is then 81 followed by 243.

I'm not exactly sure how to answer your question, but if it's any help, those numbers and all preceding results can be recieved through the function:

f(x) = 3^x
