it's different when you are learning in the classroom and learning by your own watching the video. there is no distraction here, while in the classroom there are lot thing that kills your focus. not trying to defend your teacher, but most people learn something much easier when they are 100% focus

I used to be really good at math, but since online classes have started i have gotten lazy and brain became foggy and now i cant solve math problems as efficiently as i used to but thanks to this video,i learned that i still can solve it even if it took me 8hrs of finding the correct youtube video just so i can follow my teachers formula and way of solving.

I just wanna say that most of the videos that I've seen have been people that I have observed being left-handed. These kinds of videos have helped me well, and they seem to always know math better! ?
Thank you for the amazing explanation. It was straight forward and quick and not in a confusing way,
If all my math teachers had had your patience and methodology, math would have been a wonder, not a nightmare.
Thank you!! This was really helpfully when I was trying to understand rules in sequences and patterens for my Maths exam. Why didn't my teacher teach this way? This was way easier to understand and way quicker!
OH MY GOSH THANK YOU!!! I thought this was a complicated lesson but you made it so much easier to understand! THANK YOU AGAIN!
Thank you, you really make this seem so simple and easy!This helps me a lot.
thank you so much, my teacher sort of taught us to “guess”. .you’re awesome. i knew there was a simpler way, thank you.
Thanks for such a nice lesson I really like the way you were explaining I wish that my teacher also teach like you
Very wisely and easily explained. My concept wasnt cleared from book...finally glad...thnkx
I wish i have a teacher like you..A teacher that not strict to the formula and let the student understand in the way that is easier instead of keep remembering the actual formula
Ty man my exams are coming and i needed to learn this haha tysm

I am a woman who believe that one day i will win the lottery.finally my dreams came through when i email Dr Mofar. and tell him i need the lottery numbers. i have come a long way spending money on ticket just to make sure i win. But i never know that winning was so easy until the day i meant the spell caster online which so many people has talked about that he is very great in casting lottery spell, so i decide to give it a try.I contacted this man and he did a spell and he gave me the winning lottery numbers. But believe me when the draws were out i was among winners. i won 105,000,000,00. (ONE HUNDRED AND FIVE MILLIONS DOLLARS) Dr. Mofar i truly you are the best, with these man you can will millions of money through lottery. i am so very happy to meet these man, i will forever be grateful to you.

Thank you so much for the perfect explanation, I had to help my 11 year old daughter with her homework and this helped me immensely.
I did the first problem with you (before doing any multiplication or addition; just thinking about the problem) and came up with the formula: 7+3(n-1) My reasoning is you're starting off with 7 and you want to add n multiples of 3 to it. Hence 7 + 3n, however the first term 3n must equal 0 when n is 1. Easiest way to do it? 3(n-1). The first term would be 7 + 3(1-1). The second term consequently falls into place as does the third and fourth. Now, rearranging 7 + 3(n-1), you get 7 + 3n - 3 and that my friends equals 4 + 3n. Shows you there are multiple ways of thinking and solving math problems.
Saved my life and grades! Thx so much
Really helped, Thank you! But i really have trouble finding the formula for this sequence: 3,9,27,81
@dhabecker
10 жыл бұрын
***** Yes. The formula for 3, 9, 27, 81 is 3^x, which means "3 raised to the power of x". The first term is 3, the second term is (3)(3), the third term is (3)(3)(3), the fourth term is (3)(3)(3)(3), etc. To get the answer for the 10th term you would have to multiply ten 3's.

the sequene is called geometric progression. Here the common ratio between any two successive terms is same. for ex, 9/3=3; 27/9=3 and 81/27=3, so to find the nth term the rule is a(r)powered by (n-1); here r= common ratio , n is the required term a is the first term of the sequence
I'm literally on the way to my math quiz and could not understand this for the life of me all week. Thank you!!
Man ur a life saver thanks for clearing my doubts.
And to find the plus 4 3:14 you must find the 0 term value by substracting the first term value with the commun difference so 7 -3+=4 which equals 4 and so we need to make a algerbaric expression that works with the constant which is 4 and the coeficient which is 3 and make an algeabric expression by using a algeabric letter

I learned this by doing-> The Nth term's #= 1st Term + (Nth term -1 x "reason") that would be An=A1+(n-1 x r). (r) Reason would be the number you're adding to continue the sequence. Ex as the one in the video: (7,10,13,16,19...). To find 100th term using An=A1+(n-1 x r) A100=7+(100-1 x 3) A100=7+ (99x3) A100=7+ 297= 304
