Thank you so much!! This kind of easy to understand content helps a lot, especially in a subject like mathematics. Mathematics is a broad subject and if you don't understand the basics or the simplest ways to solve the problem, you would easily lose confidence and be demotivated. You'd be more likely to quit and just shut down everything and sleep. When I attend classes to learn a lesson, I feel like it doesn't help me a lot. There's chaos, gossip, some students understand stuff before you do (which can easily make you feel inferior/weak in that subject) and it's not always the perfect environment to ask the teacher questions. I know we are supposed to clear any doubts we have by asking the teacher but it doesn't always work out. So, this kind of content by Cognito helps millions of students who struggle, not kidding!! Thank you to Cognito and the teachers, the content creators, the animators, the editors and the whole team in general. I really appreciate what you all are doing! Keep it going!
Science and maths!!! How are u this talented?🙏🙏

I have been trying to understand this from almost 1 year but , my maths teachers at school aren't that good at explaining. Tomorrow is my maths paper and you re literally a lifesaver For real, thank you so muchhh❤
out of the 7 videos your video was the only one that helped me
Without doubt the most comprehensive (and simplest) explanation on the internet - thank you!

I have a question for finding the expression,could finding the number before the first term also be negative
Love these videos, as a Maths teacher. I link these to my google classroom lesson so that students are able to revise and review at home.
This is like the best explainer videos for edexel GCSE

Blud u explain wy better than any teacher ttysm
i like this man
what a saver ! mytextbook didnt even explain that clearly
interesting been very helpful to me
What about if the difference is through division and multiplication??
Wow I knew a method to find out nth term for arithmetic sequences, but it involved making a table of values with the sequence and the nearest n term. For example if I had 5, 9, 13, 17 I would try 4n which is 4,8,12,16, and then I would know that it is 4n+1. However my method sometimes had me getting stuck, but this method is infinitely easier and faster!!! Thank you for showing us this method, loving your videos on math, physics and chem. Good luck with future videos!!

How about number sequences that has a geometrical pattern ( ×/÷ ) ?? How do you figure out what to put before 'n' in the nth term expression?
does this work with all sequences?

Haha we're glad you found us! 🙌
Another way to solve this is using the formula a(n-1)d , where a= first term, n= nth term and d= common difference. But it will only work for arithmetic sequences.
what should be do when dividing a term?
How do you guys make this animation video?
Can you please explain how to do it in fraction form
fantastic
This video explains better than my teacher
Thank you so much.I looked at so many vidoes and did not understand until I found you!
Fantastic channel, explained very well, my 10yr old is so happy to find this, said he's making her understand so easily, happy child happy mummy😁

Can I know where did the 1 came from in 4ñ+1
@isabelbarron2891
3 жыл бұрын
because in the sequence, it goes up by +4. and 5 (the first number in this sequence) is not the very start, as it is more than four. so that means you take away 4 from 5 which is 1 and that goes at the end of the equation♡
I have failed my maths exam and i had to repeate it and inshala I will get better marks Thanks alot cognito
