    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!

  • @archish405
    @archish405 10 месяцев назад +3

    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.

  • @tejaschanchal763
    @tejaschanchal763 3 года назад +1

    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!!
