1$\begingroup$ That's a very short list...any chance of extending it? $\endgroup$– luluCommented Sep 25 at 13:56

2$\begingroup$ No, I can't. Try to find a pattern $\endgroup$– Fraternal9274Commented Sep 25 at 14:22

1$\begingroup$ @Someone such as? It's unlikely that you will find one with any sort of meaningful "rule" that isn't what OP had in mind. $\endgroup$– The Chaz 2.0Commented Sep 25 at 21:12

1$\begingroup$ 38 = 5^2 + 3^2 + 2^2, 104 = 8^2 + 6^2 + 2^2, 1358 = 27^2 + 25^2 + 2^2 $\endgroup$– AltoCommented Sep 27 at 16:56

maybe the answer is: 496.192307692,
obtained by 1358*38/104, so the ratio between numbers in even positions is the same between numbers in odd positions,
example 1358/104= 496.19.../38;
also the ratio between 104/38 = the ratio between 1358/496.19....
also 1358*496.19.../104= 6479.12... so the ratio between 496.19.../104= 6479.12/1358.
we have the fomrula abab example 104/38, 496.19../104, 1358/496.19..., 6479.12/1358
