Well,accept the first one as 1;after adding 1 to each previous number starting from1,mutiply each answer by(1,2,3,4,....) one at a time. Here is what I mean!:)

& 2676=(445+1)6

Answer 2

0 x (0 + 1) 1 x (1 + 1) 2 x (2 + 1) 3 x (6 + 1) 4 x (21 + 1)
5 x (88 + 1) 6 x (445 + 1) 7 x (2676 + 1)

=>1, 2, 6, 21, 88, 445, 2676
