# What on earth is this symbol?

I'm in year 11. For the past 2 years I have only been taught foundation level maths, but recently I was entered for higher maths because my target grade is a 6. Anyway, long story short, please don't think of me as an idiot for not knowing this symbol. It has something to do with sequences. On the bottom right of the number is a little n. What on earth is that? Sometimes it has a circle above it. I've honestly never seen in it my life.

Could you take a screenshot of the symbol or something?

Just a post a pic of it.

It means the nth term. Link that may help.

But I don't know what you mean about the circle.

Yes, that's what the confusing mess in my text book looks like. I have no idea what it means or what it's asking of me, though. Nor do I understand what on earth you just said to me.

There's the circle.
The "circle" is a full stop...

It's been explained well already, but it basically means an nth term sequence.

When the "n" is replaced by a number, say 1, that means the first term in that sequence. If the number was 15, it would mean the 15th term in the sequence etc. Does that make sense?

No, but thanks for the concern. It's definitely a full stop, you'd never see a circle above the n.

When you end a sentence, you use a full stop. See? Just did it myself.

You can even compare it to full stops across the page - isn't it strange how they're identical?

Your way of 'helping me' is just instructing me. I haven't been 'helped' at all.

I accidentally 'liked' this post! Please don't take that as encouragement to continue to be rude.

If you have a sequence 3, 7, 11, 15 ...

The first term

The second term

The third term

The fourth term

Some maths questions ask you to find the term of a sequence.

In this case the term is

You're talking about the nth term right? A simple google search should help "Nth Term".
Hope this is what the problem is
