Sum of Infinite Geometric Series

[@MariosMathTutoring]

If you want a good review of sequences and series(arithmetic and geometric) see my review video on the topic here: th-cam.com/video/Tj89FA-d0f8/w-d-xo.html

Learning online has been a struggle and this video was extremely clear and concise. Thank you so much for helping me!

[@MariosMathTutoring]

You’re welcome! Glad my video helped you!

[@tirzahbruski5871]

I am a teacher, teaching from home. Thank you for producing a video that will help my students understand the sums of infinite geometric series.

[@MariosMathTutoring]

You’re welcome Tirzah! Glad to hear my videos are helping your students!

Just saved me from depression and hours of work😂😂thank youuuu 🙏🏻

[@anonymoususer5393]

Thanks, my doubt got cleared within 2 minutes. Amazing.

[@roneljamesroxas1191]

I want to know how to get common ratio if the given is the sum to infinity and the first term. Can you please tell me

[@jadzakaria7381]

Ronel 1810 bro plug in the numbers and just arrange it to equal r then your good

Way of finding 'r' is 👌👌👌
Thank you sir

Awesome Quelaire! Glad my video helped you!

What if the ratio of the sequence is multiplying by 2
For example: 10,20,40,80
How would you find the infinite sum of it?

[@MariosMathTutoring]

This video I did here will explain your question: Sum of Infinite Geometric Series th-cam.com/video/eRRjDCHlDwg/w-d-xo.html

[@bongo_baller8948]

Would the answer be no solution?
Because one of the questions on my homework was 10,20,40,80, and r=2. It was greater than the -1

[@a.sathyajothi2580]

Thank you sir.

[@jenvyclairereplente3825]

What if the ratio of the sequence is more than 1?

[@rosette_renah]

Exactly?Please sir answer this

[@tungsten_disulphide]

Just simply turn the "1-r" at the denominator into "r-1"

[@harry-fl6tf]

nice and short lecture, you saved my ass Professor

[@alemendoza2969]

In the first example you did, did you jist ignored the 1-? Because it was 1-(1/2) but you just multiplied it by 2.. Ignoring the one? Im confused. :(

[@bethanyturner2766]

Ale Mendoza since the denominator is a subtraction, you have to solve the bottom of the fraction first. If it helps, imagine a pair of parentheses around the denominator and solve like you would using BIDMAS or BODMAS. The answer in the parentheses would equal 1/2, so then he divides by 1/2, which is equal to multiplying by 2, to get 200. I hope that helps 😊

[@kashyapvishnudas1466]

Can u prove it

[@isaacsiame345]

IS 2/3 divergent

[@MariosMathTutoring]

If the ratio is 2/3 then it is convergent.

[@isaacsiame345]

@@MariosMathTutoring Alright thanks

[@k3ns3s53]

How did you get 200?

[@MariosMathTutoring]

When you divide 100 by 1/2 you get 200. When you divide by a fraction it is like multiplying by the reciprocal...hope that helps!
