A geometric sequence is a sequence of numbers in which each term is obtained by multiplying a fixed number with the previous term, except the first term. In other words, the ratio of any two consecutive numbers in a geometric sequence is equal. This ratio is called the common ratio and ...
In a geometric sequence, each term is equal to the previous term times a constant, non-zero multiplier called the common factor. Geometric sequences can have a fixed number of terms, or they can be infinite. In either case, the terms of a geometric sequence can rapidly become very large,...
