Finding the formula for a sequence of terms

You are great madar chod

Thanks

This dude is awesome, serious math teacher vibes too haha

thankfull

Can it be (-1) ∆(n-1) (n∆2+1)
Jst asking that (n+1) can be (n-1)?

Good teacher

You have a mistake in the bigining you should multiply by (-1)^(n+1)

I like your way of teaching. Mine is also the same. I like students asking me doubts in the class. It's only then that their concepts get cleared. I am from India 🇮🇳. You are doing great Job👌

Woah. Mind blown. This was so interesting to learn! I'm sure it'll come in handy next year, when we deelve deeper into arithmetic series.

Is there another way of representing instead of (-1) to the power of?

Formula=2+(n-1)*-7=9-7n

thankyouuu so muchhh

i for sure have a learning disability

wow the patience you have with those questions I would lose it

Hi, quick question. Where did the "2+1" on the second term went?

thank sir Johnny Sin

Im struggling with -6;...; 3 ;...; 15

bro this class

That last question that student asked at the end was my concern as well.... Which is: Is there another way of figuring out the Formula other than trying arbitrary methods until it works. Lol.

I was hoping that the general format of Arithmetic Progression or Geometric Progression would always easily manifest the formula, but after watching many videos, I've seen that what you all have in common is just trying different operations and mix of operations until it gives rise to the progressing terms. So I guess I can conclude that's the nature and approach of the topic Sequences & Series.
But this was nicely reasoned out though, Thankyou.

Calc 2 goes brrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!
