Etymology
Origin of progression
First recorded in 1400–50; late Middle English, from Latin prōgressiōn-, stem of prōgressiō “advancement, forward movement”; equivalent to progress + -ion
Explanation
A progression is a series that advances in a logical and predictable pattern. In mathematics, for example, the series 2, 4, 6, 8 is an arithmetic progression. If asked to give the next number, most people would reply 10. A movement forward, especially one that advances toward some achievement, is called a progression. When you get your learner's permit, it's a step in the natural progression from child to responsible adult — although you may see it as part of your progression toward freedom. The progression from permit to driver's license includes a few more steps, like highway driving and learning how to parallel park your dad's enormous car.
