i

it's k and ur formula sheet is really nice(y) but have problems in sequence don't u have any formula for that :(


There is no formula "sheet" specifically but I do know a few formulas which can help you!!

a+d(n-1) where a is the first no. of the sequence and d is the common differnce but this is only applicable for the sinple ones

There is another formula which is applicable for all.. a+d(n-1)+1/2(n-1)(n-2)

There's one more.. this is used when the ratio between the sequence is same.. i.e ar^(n-1)

thank u so much ;) and the sign / means division right?

AND PLS TELL ME WHT DOES A, D AND N STAND FOR
AND ALSO GIVE ME A EXAMPLE COZ I AM NOT ABLE TO SOLVE IT:oops:

a is the first no. of the sequence and d is the common differnce

eg if the sequence is
1.4.7.10

then a=1
d=3

and n does not stand for anything.. it s used to find the nth term!!!

eg this is how u calculate

a+d(n-1)
1+3(n-1)
1+3n-3
3n-2

ie. 3n-2 is the answer .. this is the nth term rule for this sequence.

n is the no. of the sequence u want to search for
eg.. if u want to find the 4th no. in the sequence stated above then it will be (3*4)-2 ... so 10

similarly u can also find the 100th term of the sequnce.. just substitute n by 100

thanx a lot:) but what if the difference is not common?:confused:
well I have my boards day after tom and the only thing I am having problems in is this sequence so ..

oh.. even I m giving my boards day after tomorrow and dont worry they hardly ever us sequences in paper 2... all of this is paper 4
and can u please search the rest over the net cause I hve got 2 other papers on tueday for which I hve 2 study!!!(Bio , french and maths!!!):cry:


Then u must use the formula : ar^(n-1)

where r is the common ratio.... and if this still dosent work then u must use ur mind to derrive formulas!!!
