Number Stairs (urgent)Watch
for everyone that has trouble finding the formula for any step number stairs on any grid the formula is:
n= number that the stairs starts with
x= the number of steps
g= grid (ex 10 by 10 grid, g=10)
n(1/2x(squared) + 1/2x + g+1/6 x(cubed) - g+1/6 x
if you write the formula out its much more clear.
good luck everyone.
My coursework is due in like today....but anyhelp would be appreciated cos I'm going to hand it in alfter the weekend

G = Grid size , eg a 10x10 grid=10
A = Amount of 'n'
N= bottom left hand corner of shape
in 2 steps :
1) (Sx(S+1)/2)= A
2) AN+(G+1)x((sxsxs-s)/6)= THE ANSWER
i tried out this formula can ne1 tell me how they got this? thx
