Geometric Sequence?Date: 03/21/97 at 11:17:03 From: Suryadie Gemilang Subject: Geometric Sequence? Sequence: 1, -1, 1, -1, 1, -1,... Is it a geometric sequence? Thanks :) Date: 03/21/97 at 11:30:46 From: Doctor Rob Subject: Re: Geometric Sequence? Yes, it is. A geometric progression is one of the following form: a, a*r, a*r^2, a*r^3, ..., a*r^n, ... The ratio of each term to its predecessor is a constant r. That is the definition of a geometric progression. In this case, a = 1, r = -1. -Doctor Rob, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
