(1)We will call a sequence an arithmetic sequence if there is a common difference
意思是我们称一个有相等差别的数列为算术数列,其实说白了就是我们的等差数列
如1,3,5,7,9.
(2)A Geometric Sequence is a sequence which the ratio of the common terms is equal.
The general term is
an = a1 * r^(n-1)
意思是:"几何数列就是数字间是同等比例的顺序"
说白了就是我们常说的等比数列
如:3,6,12,24,48...
就是3*2^(n-1)
