Working this out to find a formula (the long way, rather than using a program) would be highly appreciated, so I can study the steps of the process.
The sea level (as reported by satellite data) has been changing every year. Construct a formula for it (2015-2020). The sea levels are as follows:
2015 = 72.4
2016 = 83.3
2017 = 84.1
2018 = 86
2019 = 90.1
2020 = 93.2
