[Mariam879]

Can you be more specific about each letter in this formula and the whole formula and I didn't really understand the "if 1 or 2 diff. same" so could you please be more specific with one or two examples from the past paper 4

yeah it is very simple!
Vn=1/6*4 n(n+1) (2n+1)
=2/3 n(n+1) (2n+1)

 

[shazmina]

yeah it is very simple!
Vn=1/6*4 n(n+1) (2n+1)
=2/3 n(n+1) (2n+1)

tnx

As we all know, this paper will be very difficult due to the lack of hard questions in paper 2.
So the topics that are probably going to come are:
- Transformations
- Trigonometry, Mensuration..etc
- Matrices
- Inequalities and so on
Make sure you study those.

PS. Since it's probably going to be hard, does a total of 175/200 get an A*?

We don't know until they have marked everyone's paper (That took variant 22 as well) It depends on the general performance. Last year 176/200 was A* in variant 2, So aim for 180 to be safe. Good luck

Great, thanks a lot!
Do you think 180 would probably guarantee an A*?

 

[Externals]

Well can any one post the Curve of the last year ???

Yeah most likely, That's what I'm going for. My paper 2 was strong so yeah

 

[SamThomas]

can v use this formula for compound interest
principal[1+(rate/100)]^no. of years

Thats only what you have to use

tnx

ur welcum!

why do all people say that paper 4 will be hard...all iam saying is according to the pastpapers......if paper 2 is easy paper 4 is also easy its on an equal level.....and i have to say no matter how hard our paper will get..there have been harder papers

9ai) (6\8)*(5\7)*(4\6)=(5\14) this is because if you take one of white the no. of white buttons decreases by one and the total decreases by one too

ii) blue and white and white or white and blue and white or white and white and blue
so

bi)there are 25 buttons x are blue
try to find the probability of getting 2 blue buttons
the probability of getting 2 blue is in the question
write it in terms of x like this:

ii)factorise to get (x+6)(x-7)
iii)x=-6 and x=7
iv)25-7= 18 because there cant be a negative number of blue buttons use 7 instead of -6
ALL THE BEST

Thnx Bro that helps a lot now I don't need to be worried abt sequence anymore.

Thanks Alot

[Timi Adeg]

My prediction is that that 176/200 is likely to become 178/200. So set your mind to 180. Good luck to you all. Pray hard

d= the difference.
a = the first no. in the sequence.
c=the common difference (in the 2nd formula)
Hope it helps.................

 

[Ahmed Nasser]

Nth term
If you know these two formuleas then your good
dn+(a-d) (when the 1st diff is the same)
a+(n-1)d+1/2(n-1)(n-2)c (when the 2nd diff is the same)

the second one is always ryt
