Same "solution", different approach | Comment 2 of 4 |
No confidence in my answer, but it does have the advantage of agreeing with Charlie

I broke N2 up into 4 parts"

343/1/96/1
512/1/69/2
729/1/44/3
1000/1/21/4

Then the first part is N3*N3*N3, so the next in sequence is 11^3 = 1331

the second part is 1

the third part decreases by 27, 25, 23, so the next in sequence is 21 - 21 = 00

the fourth part is linear, with the next in sequence being 5

so the next N2 = 1331/1/00/5

Full answer:
10;(13,311,005);11
