In the number pathern 220.127.116.11.15.21.34
I found the recursive formula an+1-an=n+1
now i need to find a formula for n.
shouldent it be somthing like an+1=n ?
The rule should come as no surprise since is the sum of the first n positive integers ......
btw 1 (as I suggested in the other thread) you could always look into the general method of solving a recurrence relation of the form .
btw 2 it's been said that mathematics is the study of patterns. And what better way of developing this than questions like this one ......
