Abstract：Limit theory is the basis of mathematical analysis，and finding the sequence limit of infinite term sum is a difficult problem. This paper mainly discusses the formula method，the Sandwich Theorem，the definite integration method and the sum function method to find the sequence limit of infinite term sum. The application of these methods is discussed by corresponding examples.
