Cannot resist
The term still reminds me of the order in which students entered the room for geometry class; I was generally last. --Howard C. Berkowitz 21:44, 9 January 2010 (UTC)
What about zero?
It is unclear for now, whether the following sequences are geometric or not:

- Right. But what is meant by 0,0,1 ? --Peter Schmitt 16:52, 11 May 2010 (UTC)
What about q?
"...is called geometric sequence if
for all indices i." — I'd add, "and some number q (not dependent on i)." Boris Tsirelson 10:16, 10 May 2010 (UTC)
- Right. Done. --Peter Schmitt 16:53, 11 May 2010 (UTC)
More examples
An example of an infinite increasing sequence could be added. Also a constant sequence. Boris Tsirelson 10:20, 10 May 2010 (UTC)
