The thing that puzzles me, is why put "004" instead of 4?

My conclusion is possibly write the numbers backwards? In that case this would be the sequence:

576, 484, 400, 361

@Ashish Siva no,the pattern follows as the reverse of \(24^2,22^2,20^2,\) and then it should be \(18^2,?.\)the pattern \(24,22,20,18,?(16)\)

@Ayush Rai Oh ok that was my bad but 163 is the reverse order of \({19}^2\) so this is wrong too XD
