We have: 
1,2,3,2, 
A sequence is geometric if consecutive terms in the sequence have a common ratio. 
Next, let's calculate the ratio between each pair of adjacent terms in the above sequence: 
a2a1=211.4142 
a3a2=321.2247 
a4a3=231.1547 
We observe that the various ratios are not the same and that this prevents the sequence from being geometric. 
Answer: 
Not geometric
