It seems like you are asking for help with a table that relates to the number of days (represented by \(x\)) and the number of texts (represented by \(y\)). However, the information you've provided is incomplete.
To better assist you, could you clarify what the relationship is between \(x\) and \(y\)? Is there a specific formula or trend you would like to apply? Or are there specific values you would like to fill in for \(a\), \(b\), \(c\), and \(d\)?
If you provide more context or data, I'd be happy to help you fill in the missing parts of the table!
