How do you find the formula for the nth term of an arithmetic sequence

👉 Learn how to find the nth term of an arithmetic sequence. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. An arithmetic sequence is a sequence in which each term of the sequence is obtained by adding a predetermined value, called the common difference, to the preceding term.

The formula for the nth term of an arithmetic sequence is given by An = a + (n - 1)d, where a is the first term, n is the term number and d is the common difference. We can obtain the common difference by subtracting a term from the succeeding term or if the known terms are not consecutive, we can obtain the common difference by dividing the difference of the two terms by the difference of their term numbers. Plugging the required values into the formula, we can obtain the required nth term of the arithmetic sequence.

yes sorry I did not have the right cable plugged in, I think head phones work best but I could hear it just really low, sorry. I have fixed the problem

[britanaforbes]

You explain this way better than my teacher, if only you could be my algebra teacher

[MikeOtranto]

Great video! I was confused as to what "an" meant and how to find a1. Thanks for posting.

[xaquaxchaosxx]

Yo brian! you are the Thanks for the help my bald G! Keep killin it out

[arbindkumar]

thanks sir ....your videos are amazing and very easy to get

[ProbablyTheHappiestLoner]

Thanks, our math teacher didn't explain how to do this, so I had to figure it out by myself. I was close on the solution, with the substitution on the (n - 1) part, but I did get the right answers.

I searched for a problem i couldnt understand and ah, new school year, same teacher🤩💝

[mohdmikael-ozer]

What do you call "an" A sub n or ace of n ?

[santoshvamdev]

cant we find a and d by substitution method?

[ibtisaamahmed]

And the video was awesome helpful and simple but complicated you get what I mean

[sofya]

Please increase the sound of the video

[miso]

easy :D (i watch for improve math vocalbulary not for math :D). Do you hear you voice with enough volume? I option all my sound options for max. volume but it was not enough.

[howoooowoh]

I swear that if I graduate. I'll be mentioning your name and not my teacher's.
