If you are searching for Progression Formula List and Definition in Math then you reached the right place.
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d, and so on. Thus nth term of an AP series is Tn = a + (n – 1) d, where Tn = nth term and a = first term. Here d = common difference = Tn – Tn–1. The sum of n terms is also equal to the formula where l is the last term.
