"WebSome are quite easy to understand: If r = 1 the sequence converges to 1 since every term is 1, and likewise if r = 0 the sequence converges to 0. If r = − 1 this is the sequence of example 13.1.7 and diverges. If r > 1 or r < − 1 the terms rn get large without limit, so the sequence diverges. If 0 < r < 1 then the sequence converges to 0.
