dessskris Posted January 22, 2011 Report Share Posted January 22, 2011 I am just asking about geometric sequences in general.We define a geometric sequence as follows, right?a, ar, ar2, ar3, ar4, ar5, ..., arnIs there any limitation on the values of a and r? Or particularly, can a and r be zero? If a and/or r are/is zero, would the sequence be considered a geometric one?Thanks a lot beforehand!

fan Posted January 22, 2011 Report Share Posted January 22, 2011 (edited) No i do not think there are any limitations. a and r can be any value.. However I do not think you can get a geometric sequence with a ratio as zero.cause remember to find the ratio we normally divide the second term by the first term. or the third term by the second term,.. etc lets take for example:0,2,4,8,16we get a as zero however this would not work as a geometric sequence because the value of r is not consistent.4/2 = 2, 8/4 = 2, 16/8 = 2, However 2/0 is undefined..Hope that answers your question Edited January 22, 2011 by fan 1 Reply Link to post Share on other sites More sharing options...
