3³/2, 3²/1, 3×2, 1×2², 2³/3
We have the product of two series: 3³, 3², 3¹, 3⁰, 3⁻¹ and 2⁻¹, 2⁰, 2¹, 2², 2³. The exponents of 3 start at 3 and decrease by 1 for each term, while the exponents of 2 start at -1 and increase by 1 for each term.
The sum of the exponents is 2. The general term is 3⁴⁻ⁿ2ⁿ⁻².
The next term would be 3⁻²×2⁴=16/9.
