Is there anyway to calculate the following? As you can see when the first number increases the 2nd number only increases a little bit. I would like to calculate the other numbers with the same reference. Thanks

6.6162 = 2.598

11.2262 = 2.939

9.2362 = ? ( I know is around 2.7 something)

4.9068 = ?

2.7659 = ?
