(Naturals^m; m=1,2,3....) m=1: 1,2,3,... and make the sum of pairs (1+2),(3+4),(5+6)... we get: 3,7,11... Now find the difference of pairs: (7-3),(11-7),... we get 4,4,4,4,..... Now do the same for next exponent, m=2: 1,4,9,16... getting 5,25,61... that is (1+4),(9+16)... and the differences 20,36... we get 16,16,16,16,... m=3: ... we get 96 and so on. |
