There are two other persons who asked this same question.

mdavidroth answered it this way

... if you do a cubic regression, you can get the series...

a(n) = -(19/90)n^3 + (353/90)n^2 - (908/45)n + 607/15

If you plug in 1 for n, you'll get 24,

If you plug in 4, you'll get 9, and so an and so forth...

The missing values have n = 2, 3, and 5

a(2)*a(3)*a(5) = (127/9)(143/15)(506/45) = 9189466 / 6075

Good Luck

Answer 2

actually its not math , the only math part is the multiplying, the other numbers are in sequence on a site on neopets , and have nothing to do with math!!! so if you want the answer for lennys conundrum than ask for it and dont lie about where you got the question from
