在黄皮书官方指南上P164 有个数学题具体为：on a scale that measures the intensity of a certain phenonmenon , a reading of n+1 corresponds to an intensity that is 10 times the intensity corresponding to a reading of n. On that scale, the intensity corresponding to a reading of 8 is how many times as great as the intensity corresponding to a reading of 3? 答案是10的5次方。我看不明白，这个几何级数怎么表达出来的？求解
