摘要
定义了n元等比数列、n元等比级数,给出了它们的通项公式及前n项和.并解决了多元等比级数的敛散性问题,求出了多元等比级数的和.指出了多元等比数列及多元等比级数在特殊情况下与一元等比数列及一元等比级数的一致性.
n-ary geometric number sequence and n-ary geometric series are defined and their formulas of general term partial sums of forst n term are given. Their convergence and divergence n-ary geometric series are solve. This essay points out the goemetric nember sequence the geometric series are special condition of n -ary geometric number sequence and n-ary geometric series.
