Be careful. Recurrence sequences do not have same common difference.


For c1 they do

This is for Edexcel

In that specific question however, there is a common difference of 4 between each term, you end up with 2,6,10,14,18... and so on.

I am retaking C1 and I hell hope something reallly stupid doesn't come up. I can usually deal with hard questions but not extremely hard unheard of ones.
I hope I get 95-100 UMS though.

The recurrent sequence is an arithmetic sequence in disguise. I gave that a2 = 6, and asked to work out a1 and a3, which were 2 and 10, so that's how the connection is made :tongue: they can check a4 if they wish.

Okay this is a really silly C1 question but nobody's mentioned it to me beforeWhat order would you do indices in? I know theres BIDMAS ofc but for example:x(2x^-1/4)^4 What order would you do the indice rules in? Does it not matter? Why do we save the multiplication of X till last, because of BIDMAS.. just need clarification
Just a quick question; what's 4 over the square root of X as an indicie and why??

4x^-1/2

rootx=x^1/2

1/x =x^-1

do the math
4*x^-1/2

Here is a question for you to try :h:


A sequence of numbers a0,a1,a2,... a_0, a_1, a_2, ... is given by an+1=2an+6−4n a_{n+1} = 2a_{n} + 6 - 4n.

Given that a2=6a_2 = 6, find a1a_1 and a3a_3.

Hence find the value of ∑i=110ai\sum_{i=1}^{10} a_{i}.

Hence, or otherwise, find the value of ∑i=010ai\sum_{i=0}^{10} a_{i}.


Is the last part just 198 or am I being stupid?

Yes, it is just 198 and you are not being stupid :h:

mate no one will know, you should be comfortable with everything by now
Hey is doing topics by question for maths enough revision? Cos it gives me a good understanding of how to tackle any question that comes up for that topic and you basically cover most papers through it. I've left my revision last minute and want to move from a d to a b

no I just mean in general, what is the most difficult type of question that can be asked, not what you think is going to be asked
