Title: Maths Question...Plz answer
Post by: I Jimmy I on May 05, 2009, 08:46:50 pm

Sup Every1,
Guyz I'm having a doubt in Maths P4(as usual)
At the end of the paper, we usually get a question concerning the 10th term and nth term, etc.
Now my question is...
To find the nth term there are certain formulas to consider...
I want THOSE formulas...
And guyz there are 3 formulas....
1 concerning the 1st diff and 2 concerning the 2nd diff and 3 concerning the 3rd diff...
WHAT ARE THE FORMULAS FOR EACH DIFFERENCE...
Peace!!
