An introduction to geometric sequences

Missed the previous lesson?

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

I'm only now learning this in college calculus. You guys in 8th grade who know this deserve a medal or something.

[Hammersmashedd]

I should be paying you instead of my useless college.

[dresthon]

Isn’t it so great being put into an advanced 7th grade math class so you can cry over this at 3am the day before a test

[stevenf]

I have looked everywhere just to find out a non formal definition of a geometric sequence and you sir have rocked my world...

[speedybast]

how can you write so well on a computer program!?!?!

[jcurrell]

Found these while studying for finals. Will use these for the rest of my engineering math classes. Thank you Sal!

[mariyah]

I literally stopped paying attention for a second an now I'm lost

[mialaure]

Thank you, so much, literally I take 8th grade Algebra1 and this is all so new to me, and I move in a slow pace so I end up not understanding most of the topic and I end up having a hard time with it. But your video has made this so much clearer and I'm just so thankful right now :)

[calen_chan]

I was just going to say the same thing! You beat me to it. :)

[giannaphillippi]

If i could just sit down in a class with you and you were my teacher, I might not be failing!

[Goofmobber]

Whenever I hear your voice explaining a subject, I already feel better about it... :D

[olgaslavkov]

When you don't even need your math teacher bc khan explains it better than your dad.

[sleepingkenny]

anyone else feel in love with this guys voice

[Raza__]

Your voice is so clam and soothing Khan. I smile the whole time when I am watching your videos. 😄

[lanazenney]

thank you for saving me during junior year. you rock.

[rapever]

omg!!! just in time sal!!! my class is doing arithmetic sequence and soon geometric sequence soon... thank you soo much

[aramanthine]

Sir, I would like you to be my math teacher.

[dieforyou]

i feel like my brain is still stuck in grade 7
i can never understand this unless I solve like 50 questions on it :(

[mervynwinn]

this is surprisingly simple and I'm in 9th grade

[MagICskattER]

Sometimes i think of bunking class and sitting on Youtube and stare at Khan Academy Videos
all the time!!!!
FUN, UNLIMITED PRACTICE AND BETTER KNOWLEDGE!!!!
Easy to
