12 Series

12.1 Use the binomial theorem for expansion of (a + b)^n for positive integer n.

12.2 Use the general term

12.3 Recognise arithmetic and geometric progressions and understand the difference between them

12.4 Use the formulas for the nth term and for the sum of the first n terms to solve problems involving arithmetic or geometric progressions

12.5 Use the condition for the convergence of a geometric progression, and the formula for the sum to infinity of a convergent geometric progression
