General Term tn＝t1＋d（n-1)

Arithmetics sum Sn＝n(t1＋tn)/2

General Term tn＝ｔ１×r＾2-1

Geometric sum Sn=t1(1-r＾ｎ)／1－r, r≠0

Infinite Geometric sum S∞＝t1/1-r

I learned these formula.

This week I learned Function Notation.

Function Notation is used to replace the mapping notation f: x→2x+3. Under a function f, the image of an element x in the domain is denoted by f(x), which is read “f of x”.
