anyone can help me now?

create equation from ;
0 , 2 , 0 , 2 , 0 , 2 , 0

please help me~

Well that could be very simple indeed.
What do you think ?

Can u help me with the answer? I blur right now~

Any equation? Times or division or anything?

nope.. that's all.. create equation from that sequence.. can u answer it?

Of course I can! Have you studied your times tables and know them? If so, you should be able to answer it too.

Actually this question from my friend.. I finished my study so long already.. forgot about the concept.. make me blur~ >.<

Wait a minute!! Who needs to know the answer to this math equation?

Each number is two minus the previous number. So given N_0 = 0, then:


N_i = 2- N_{i-1}


for i = 1, 2, 3...

Or you could use the modulo operator:

N_i = 2 \times mod(i,2)

for i = 0, 1, 2...
