Video transcriptIn this video I want tointroduce you to the idea of a geometric sequence. And I have a ton of moreadvanced videos on the topic, but it's really a good place tostart, just to understand what we're talking aboutwhen someone tells you a geometric sequence. Now a good starting point isjust, what is a sequence? And a sequence is, youcan imagine, just a progression of numbers. So for example, and this isn'teven a geometric series, if I just said 1, 2, 3, 4, 5. This is a sequence of numbers. It's not a geometric sequence,but it is a sequence. A geometric sequence is aspecial progression, or a special sequence, of numbers,where each successive number is a fixed multiple ofthe number before it. Let me explain whatI'm saying. So let's say my first number is2 and then I multiply 2 by the number 3. So I multiply itby 3, I get 6. And then I multiply 6 times thenumber 3, and I get 18. Then I multiply 18 times thenumber 3, and I get 54. And I just keep goingthat way. So I just keep mu...
