WebThe notion of limits can be defined for sequences valued in more abstract spaces. One example of a more abstract space is metric spaces. If is a metric space ... Then the sequence is said to uniformly converge or have a uniform limit of if with respect to this distance. The uniform limit has "nicer" properties than the pointwise limit. ... WebFor r = 0 the limit is obvious 0. Now let r ∈ ( 0, 1), we can write r = 1 p with p ∈ ( 1, ∞), So. r n = 1 p n = 1 ( 1 + p − 1) n ≤ 1 1 + n ( p − 1) ≤ 1 p − 1 ⋅ 1 n. For r = 1 the sequence converges to 1 as it is always 1. Now we have to check r < 0. r n = ( − 1) n ( − r) n.
