波利亚曾说过:“解题的成功要靠正确思路的选择,要靠从可以接近它的方向去攻击堡垒.”因此我们解答数学问题关键在于掌握思考问题的方法,思维方法正确,问题就容易解决.常数数列是数列中的最特殊数列,是指一个数列的每一项都为一个相等的常数,也叫“常数列”.在解题过程中我们利用条件可以构造出常数列,从而减少计算量,大大地提高解题速度,起到事半功倍作用.一、构造常数列巧求数列的通项公式
Polyana once said: “The success of a problem depends on the correct choice of thinking, and it depends on the direction of approaching it to attack the fort.” Therefore, the key to solving mathematical problems lies in the way we think and think in a correct way , The problem is easy to solve.Continuous number sequence is the most special sequence of numbers, refers to a series of each an equal constant, also known as “constant column ” in the process of solving problems we can use the conditions can be constructed Out of constant columns, thereby reducing the amount of computation, greatly improve the speed of problem solving, play a multiplier effect.
