Sequences and Series (Arithmetic & Geometric) Quick Review

Quickly review arithmetic and geometric sequences and series in this video math tutorial by Mario's Math Tutoring. We discuss the formulas for finding a specific term as well as the formulas for finding the sum of the series. We discuss the notation as well as recursive formulas for both arithmetic and geometric sequences. We also discuss summation notation and solving systems of equations when given 2 terms.

POV: You don't pay attention in Math and have a test the next day which is why you came to look for a review

I just learned more from this Video than my teacher has taught me in the past week in the first 59 seconds.

You're an awesome teacher. You explain what's actually happening during the process instead of just showing how to do it. This is so important for getting an intuitive understanding of what's really going on... which is the only way that I can learn anything.

My test is tomorrow so this is a huge lifesaver

Keep up the good work 👏👏

Thank you, learning math through online curriculum is tougher than I thought, you really help make distinctions and metaphors that I would normally use; reading does not do the same thing.

Tomorrow's my exam and I had to have a quick revision and this video helped me revise every single formula in just 19 minutes! Love how U can revise a long ass chapter in less than an hour whereas other youtubers take 1-2 hours and even advertise their channel. It's cool how u had no intro and dived directly into the topics which shows how u chose quality over quantity... I'm subscribing right away... and it's amazing how teachers from my own country (India) find it time taking to show the entire process and you can do it in minutes! Thanx Mario!!!! Your video's really a life-saver! NO cap!

THANK YOU! Absent for a few days and you caught me back up

[seemarida]

this lesson is taught to students in middle school and continues in high school. not one teacher explained to me where the formula comes from. this helped a lot, thanks

[zeynepbaykut]

Why would people dislike??
Awesome love it♥️

[rororin_mochikoko]

Online classes suck so bad, I'm just glad youtube has this kind of videos to save my ass.

[glasslicker]

Thank you so very much, I had to figure out the “Euclids’ method” for adding the sums in a geometric series, and your formula [Sn=A1(1-r^n) /1-r ] was very helpful in having me understand my teachers’ teachings.

[cazietodd]

I really love the way you explain where the formula for the arithmetic sequence came from! I am a math teacher and I will definitely be using that from now on! I am a big fan!

[leenabuaisheh]

Online classes have been so difficult and is a full-on lifesaver

[epicfunnyvideos]

Three years later and students are still benefiting from this video.. This video taught me more than my school teacher haha... All the best!

[justachildofGod]

It’s super hard to pay attention in class so I usually study on my own, but I didn’t understand, but when I watched this video, I understood!

I don’t know how you teach it because this is really similar to the way my teacher taught it, but I only understood your way. Thank you so much

[samhenson]

I really like how he explains the problem without adding the formula at first and then shows how it ties in to the formula, It makes so much more sense slowly adding in the variables

[rehamalfandi]

Thank you so much, I almost cried when I couldn't find anyone to help me with this in my native language, but then I found you, my savior. 😊
And I study at home, so it's a difficult situation.

[oluchiokoli]

Thank you so much for this! I had no clue how to do this especially because of all the disruptions in teaching due to COVID-19 but you explain everything so well!

[ezekielgarcia]

Our education learning in Ph is non, teachers are not teaching nor presenting something, they're just giving us modules to comply, Thank you for teaching us sir
