GOODY.... ONE MORE way
this is like an array
so, idhoda frst row shud b
1 2 3 6 6
cos 2 x 3 + 2 x 0 = 6 + 0 = 6
same way,
1 2 3 6 6 (2x3 + 2x 0=6+0= 6)
2 3 4 15 12 (3x4 + 3x 1= 12+3= 15)
3 4 5 28 20 ( 4x5 + 4x 2= 20+8= 28)
4 5 6 45 30 (5x6 + 5x 3= 30+15= 45)
5 6 7 66 42 (6x7 + 6x 4= 42+24= 66)
6 7 8 ? 56 (7x8 + 7x 5= 56+35= 91)
7 8 9 120 72 (8x9 + 8x6= 72+48= 120)
