几何级数, 等比级数
a mathematical series in which the ratio of each term to the preceding one is constant
示例:
•
The sum of an infinite geometric series can be calculated if the common ratio is less than one.
如果公比小于1，就可以计算无穷几何级数的和。
•
In a geometric series like 1 + 2 + 4 + 8, the common ratio is 2.
在像 1 + 2 + 4 + 8 这样的几何级数中，公比是 2。
