1?

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.
