利用几何直观裂分数式求解一类数列问题

Using the Geometric-intuitive Split Math Formula to Resolve the Question of a Certain Enumeration

通过裂分数式为无穷递缩等比数列,实现合成与分解、有限与无限的转化,培养发散性思维、创造性思维、几何直观思维。

Using the geometric -intuitive split math formula as a infinite decreasing geometric series, realize the transform between the synthesis and decomposition, the finite and infinite, to train the divergent thinking, the creative thinking and the geometric - intuitive thinking.
