Finding the Sum of a Finite Arithmetic Series

In this video, I show two formulas to find the sum of a finite arithmetic series and do two examples of finding some sums!

I graduated from college already, I saw this sum sequence problem from tiktok to ask whats the sum from 1 to 100. Then I am going straightly to Patric. Its still so impressive for me once i learned this knowledge again. Thank you Patric, i gained my knowledge again whenever i wanna study. Its you always there!!

what makes a great teacher is the ability to impact knowledge in a way that is practical, therefore making it part and parcel of your students forever. I have sat under a lot of math teachers...a lot of geniuses in math (THEY KNOW MATH!!!). But none of them brings math to their students the way you do. You make it look so easy.... as a matter of fact, you make them easy. All of your tutorials I have watched over years have made me, by far, a better math student than my mates. May God bless you!

My math teacher sent me here... You know your great when a math teacher suggests you and uses your videos as part of their lessons!

I was nearly crying in desperation. It's 2AM, and my mom stuck me in an Honours Pre-Cal class. A short week (4 days) and she taught us Arithmetic Sequences, Arithmetic Series, Geo Sequences and Geo Series and wants a test in... well, about eight hours. So, I fucking love you, man. Another thing you have that my teacher doesn't: a rewind button.

Praise be to thee Math Wizard for thou hast shown me the light in the cavern of numbers

Thanks Pat! You're very helpful...actually you are more like a math hero. Well done! This material is becoming more clearly understood because of your instruction. Have a wonderful day.

My teacher "taught" the class this for 30 minutes and I failed to understand it whatsoever. You took 10 minutes and now I completely understand it. Thanks!

@Truwarier14 pretty sure i have a video on it

Mr. Patrick, YOU are the greatest math teacher I've ever seen. Although not in personal but... I've really learned a LOT, and actually I also hate our math teacher cause she's like "copy this in your notes, study, then we will have an activity tomorrow".

just trying to give an extra resource for people :)

[keirairia]

hi! i'm starting online classes soon and your lessons have been a great help to me and is very easy to understand. thank you very much for sharing it to us😄. i'll be depending on your lessons from now on.

[Cenabetimam]

I've been getting it wrong where you pointed out with question b..makes sense now...thanks so much!

[patrickjmt]

@fifa08ronaldhino not that i am aware of : )

[patrickjmt]

@HearTheBlue well, you would somehow have to be able to deduce the number of terms from the info given, otherwise i can not see how you would do it.

[SangsooHatesYou]

thank you so much! I had to double check before I take the finals today. I have it in about 6hours from now

[patrickjmt]

@PeterKang1284 an infinite arithmetic series would not have a finite value.

[cathyalvarez]

Thank you so much it help a lot like us teaching in Math ..thank you so much GOD BLESS....FROM Phillipines

who needs to pay attention in class when you got pat, great videos btw!

[davemartin]

Great video. Very useful as the rest of your videos are. A truly outstanding resource.
Almost not worth mentioning: multiples of 9 will have their digits add to 9.
9*115 = 135

You are such a great teacher. God bless you!
