Based on prior knowledge, we can analyze the relationship between the "balance" feature and the task of whether the client subscribes to a term deposit or not. 

Typically, clients with higher balances might be more likely to subscribe to a term deposit, as they have more disposable income and could take advantage of the benefits of a long-term investment. On the other hand, clients with lower balances may be less inclined to tie up their funds in a term deposit.

To generate the dictionary, we will consider 5 typical balance values for each target class ('no' and 'yes'):

```json
{
    "no": [0.0, 100.0, 500.0, 1000.0, 2000.0],
    "yes": [5000.0, 10000.0, 15000.0, 20000.0, 25000.0]
}
```

These values are just examples and should be adjusted based on the actual dataset and distribution of balance values.
