Solution Explanation for the Puzzle Answer Comment 9 of 9 |
(In reply to Puzzle Answer by K Sengupta)

The given sequence S(n)(say)  is defined by:

S(n) =C(n) - T(n)
where: C(n) = n^3, and: T(n) = 2^(n-1)
Then:
S(1) = 1-1=0
S(2) = 8-2=6
S(3) = 27-4=23
S(4)= 64-8=56
S(5)= 125-16=109
S(6) = 216 - 32= 184
S(7) = 343-64 = 279
S(8) = 512-128= 384
S(9) = 729-256 = 473
S(10)= 1000-512=488
S(11)= 1331-1024= 307
S(12) = 1728 - 2048 = -320

Consequently,  the required next two (missing) number in the sequence is 307 and -320.
