eh ? :p



n(n+1)
   2

for n=1,2,3...

That works for the first pattern. The sequence begins with 1, i.e. 1, 3, 6, 10, 15, 21, 28 etc.

(Triangular numbers btw.)

ehm neither work for 1=n...
p = (1+2)(.5+1.5) = 3*2 = 6
p = (1(1+1))/2 = 1

and it starts with 3...

the correct one is ((n+1)(n+2))/2
All sequences start at zero, even JA knows that... :dodgy:
the ones in the example didn't :P
They start with n=0, fool :P
He said, initial value is 3. Implies for n=0, value=3; Then next value is 6 implies for n=1, value=6.

markee, the JA knows * :P
