1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900, 961 ... :d

1 = 0
9 = 1
36 = 2
100 = 3
225 = 4
441 = 5
784 = 6

Congrats Naimish!!
U r right I guess.

Actually, the diff between numbers is as below

9, 3x3x3, 4x4x4, 5x5x5, 6x6x6, goes on

So for next number the different should be 7X7X7 = 343
So to derive diff as 343, just add the the previous num i.e. 441, next will become 784
