1@Satyajit you are a Transposer! :P
How will you arrange all the digits from 1to9 forming different digits such that they form an A.P.?
For example,consider 147,258,369. They form an A.P. with common difference 111,and all the digits from 1 to 9 are used . form another one?????

if you write all the digits from 1 to 9 as
1 2 3
4 5 6
7 8 9
and take nos. from any side , say 321,654,987,then they form an A.P.;again take 963,852,741,they also form an A.P.........
