best fit means that you plot on the points that are making sense and ignore any point that is either out of the way or is changing and ruining the shape of the graph.Hey guys ! Simple question !
How do i draw a line of best fit ??
Thank you ! Btw do we have to take the mean of the points and plot a line that passes over it ??best fit means that you plot on the points that are making sense and ignore any point that is either out of the way or is changing and ruining the shape of the graph.

HeyCan someone please help me with the this: Question 9(b)

It's a sequence question, the answer in the ms is 360x^2. I just can't find the method to it or it's nth term.
Thanks in advance.
Hey
So specially in sequences you need to pay lots of attention towards the numbers and the question itself. First of all they didn't ask you for the nth term so no need to find, it is even difficult to find it. However for the first sequence you need to add the two preceding terms. The second one , the powers of x decrease by one as you go further therefore it will be x^2 . Moving on to the numbers, if you divide 120 by 30 you get 4 , if you divide 30 by 6 you get 5 and finally if you divide 6 by 1 you get six. So the number get multiplied by numbers which go on decreasing by 1
Therefore if you multiply 120 by 3 you get 360. And as the powers decrease you get x^2 . Put them together you get 360x^2 .
Dont worry ! I am giving maths also this year with you BTW Which variant are you and which school/country ??Impressive, that makes sense, I have no idea how I would notice of such a pattern in my upcoming exams(this year).
