All language subtitles for 2. n-th Term of Arithmetic Sequence - Question

Welcome back, ladies and gentlemen, my name is Vlad, and in this exercise, what we are going to

do is simply to calculate the anthe term of a given arithmetic sequence.

So what do you have to do is to simply write a program that calculates and prints a m.

OK, so the F term of A given arithmetic sequence.

OK, so just based on the previous video that you hopefully did not skip, we have to calculate this

anthe term.

So what we will be given basically is just this sequence.

OK.

And it has, it has we know first of all, we know where is the laser.

But what we don't know is the value inside of these and terms.

So that's something that we have to find out for ourselves because we don't know it.

And although we could have just calculated it manually every time just by adding the value of two again

and again and again until we reach out the ninth element.

OK, but that's just tedious work, not to mention the fact that there may be really large sequences,

that it's not going to be that easy to calculate.

And basically that's why we need to have some formula that we can use for that and not do all of this

messy work.

So if we want to take a look at how this rule is applied, we can simply use these formula right here

to calculate this is a given mathematical formula that we simply can take and use it for our needs or

basically to use it in order to find the term of the sequence.

So this formula goes like this.

If you want to find the term of this of this arithmetic sequence, you have to, first of all, know

a one.

And that's something we know you have to know in.

And it's something we know.

We know the number of elements in this arithmetic sequence.

And also we have to know the difference between any two consecutive elements.

So D is also known and is two.

So there is no problem for for us to calculate and to find the term of this sequence.

But just to give you more confident and just to show you additional example and equals to any one plus

and one minus one and minus one multiplied by D.

And if we want to simply dig these values, put them inside of here.

So it will look like this.

A one is one, a one is one plus nine minus one and is nine.

So we just replace a variable with nine value.

Two is the difference.

And there we go, one plus eight multiplied by two and one plus 16 equals to 17.

So that's how we find the anthurium.

Basically we already remember that it's exactly what it should be that just now we used it to find the

theorem.

We used some formula, some mathematical formula, and basically that's it regarding this explanation.

And while that's all good, we are not at a math gap.

We are at a programming class, a programming tutorial.

So what we have to do right now is to write a program that calculates and print this and term based

on some some combination of these values that will be given to you.

So give it a try.

Take at least 10, 15 minutes to think about it and try to solve it on your own.

And once you are ready to compare your results with my solution, feel free to move on.

So until next time, until I see you in the solution.

Good luck, guys, and let me know if you like this video and if you have any questions left.

This is Alphatech, and I'll see you next time.
