Write the missing fraction in the pattern: 1/12, 1/27, 1/6, 1/9, ?, 1/3

Question

 What is the pattern?

Answer 1

1/(3×2²)   1/(3×3²)

1/(3×2¹)   1/(3×3¹)

1/(3×2⁰)   1/(3×3⁰)

The missing number is 1/(3×2⁰)=1/3

Answer 2

The pattern I see is that numerators are always 1, and denominators are

3•4   3•3   3•2       3•3   [3•2]   3•1   where the one in square brackets is inferred after severe scrutiny.

 

So I'll say the missing fraction is 1/6.
