Based on prior knowledge, we can assume that the balance feature represents the amount of money in the client's account. To analyze the relationship between the balance feature and the target variable (subscription to a term deposit), we can look at the average balance values for each target class ('yes' and 'no').

Here's the dictionary with the specific details:

```json
{
	"no": [100.0, 200.0, 300.0, 400.0, 500.0],
	"yes": [1000.0, 1500.0, 2000.0, 3000.0, 4000.0]
}
```

This dictionary indicates typical balance values for the target classes 'no' and 'yes'. The 'no' class has lower balances ranging from 100.0 to 500.0 euros, while the 'yes' class has higher balances ranging from 1000.0 to 4000.0 euros.
