An illustration of limit top-quality and limit inferior. The sequence xn is shown in blue. The 2 pink curves solution the limit superior and Restrict inferior of xn, revealed as dashed black lines. In such cases, the sequence accumulates throughout the two limits.
When the standard limit exists, the limit inferior and limit remarkable are equally equivalent to it; consequently, Every single could be deemed a generalization in the standard limit which can be principally attention-grabbing in conditions wherever the limit isn't going to exist.
