the sequence is 6, 4, 2

the recursive formula is tn = (tn-3 + tn-2) x tn-1

so I did it = (2+4) x 6 = 36

and i got 2,068, 416 for t7

but it's not right and now i'm not sure how to solve it. (Doh) - Jan 4th 2009, 12:40 PMskeeter

Sorry I didn't post my question clearly, still getting the hang of codes. - Jan 5th 2009, 02:06 AMearboth
