Explanation:

No pattern immediately jumps out, so I'm going to mess around with the numbers for a bit until I can spot it.

Writing as fractions:
3/2, 9/4, 27/8 possibly a pattern there... The denominator is going up in 2^n, and the numerator in 3^n. So the one before that would be 1/1=1 which doesn't really fit... also this pattern is taking 3/2 to be n=1 so there can't be one before it.
