Abstract Limit of a sequence refers to with the infinitely increasing， infinitely close to the results of an arbitrary constant， it reflects a limiting process. This paper mainly discusses on the basis of the definition of the limit of a sequence and its important properties extends several conclusions， and the conclusion is proved.
