从函数的观点看,数列的实质是定义在正自然数集或它的子集上的一类特殊函数,是函数概念的进一步延伸.因此,我们在解决有关数列问题时,应站在函数的角度,高屋建瓴,充分利用函数的观点,以它的概念、性质、图像等特性为纽带,架起函数与数列间的桥梁,揭示二者间的内在联系,从而 From the point of view of function, the essence of a sequence of numbers is a special class of functions defined on the set of positive natural numbers or its subsets, which is a further extension of the concept of functions. Therefore, we should stand at the point of view of functions when solving problems concerning sequences of numbers. , High-level housing construction, taking full advantage of the point of view of function, with its concepts, nature, images and other characteristics as a link, erecting a bridge between functions and series, revealing the intrinsic link between the two.
