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 · 7 months, 4 weeks ago

Yes, the answer should be 423 @Lakshya Singh · 7 months, 4 weeks ago

Why is that? · 7 months, 3 weeks ago

It follows the series of decreasing perfect squares writyem in reverse order. · 7 months, 3 weeks ago

and the answer should be 652 · 7 months, 3 weeks ago

no,the pattern follows as the reverse of $$24^2,22^2,20^2,$$ and then it should be $$18^2,?.$$the pattern $$24,22,20,18,?(16)$$ · 7 months, 3 weeks ago

Oh ok that was my bad but 163 is the reverse order of $${19}^2$$ so this is wrong too XD · 7 months, 3 weeks ago

actually the question should be 675,484,004,423,? · 7 months, 3 weeks ago
