If the question requires us to choose either even pattern or odd pattern, I will choose "even pattern".

My assumption:
Even pattern = regular pattern
  As the number line is a single multiples of 3, the pattern is regular to me
Odd Pattern = special or irregular pattern.  That means, we are unable to predict what no. come next.

Need comment from others as well.
