Why are you doing paper 2? .-.

 

[DaniyalK]

That's a big formula :/ For changing difference. Is this a part of our syllabus?

No, like others said, you can just figure it out through trial and error. The formula is just a more consistent method.

Whats the year and question?

Oct-nov 2005, question 6(b)

 

[funky brat]

There's a formula, use that.
a+(n-1)d1
a is the first term of sequence and d is the common difference.

Sorry. .-. This is for the single common differnce. For this there's another formula.

Oct-nov 2005, question 6(b)

The trial and error isn't working here. ^^

Oct-nov 2005, question 6(b)

It is (n+2)(n+1)/2

Just apply some formulas and find one that settles in

Paper 2 :/ Don't we have paper 1 on monday?

nope paper one

Ok i finally got it.In such complex patterns there is always a hint given in the above sequence and we have to make a relation with the one above and the one we have to find,this is a rule.So here we can see that each number below is increased by n and +1 e.g 2nd was 3 in first pattern but in next it was 3+2(number of sequence) + 1 and so on.Hence we can insert this in the formula given above to derive it.Final formula would be

(n+1)(n+2)/2

getting me?

 

[***amd***]

How? .-.

observe how is every next term changing.

In question 15 , do we have to ensure that the length and the width must equal to 39 since he has a total of 39 fences or we just need to put up some ransom values and then calculate the areas?
