10
10 *1 7*1 = 17
17* 2 7*2 = 48
48*3 7*3 = 165
165*4 7*4 = 688
688*5 7*5 = 3475
3475*6 7*6 = 20892
7 16 41 90 171 ?
7
7 + 3^2 = 16
16 + 5^2 = 41
41 + 7^2 = 90
90 + 9^2 = 171
171 + 11^2 = 292
12 14 32 102 416 2090 ?
12
12*1 + 2 = 14
14*2 + 4 = 32
32*3 + 6 = 102
102*4 + 8 = 416
416*5 + 10 = 2090
2090*6 + 12 = 12552
1 3 24 360 8640 302400 ?
1
1 * (4 - 1 ) = 3
3 * (9 - 1 ) = 24
24 * ( 16 - 1) = 360
360 * ( 25 - 1 ) = 8640
8640 * ( 36 - 1 ) = 302400
302400 * ( 49 - 1 ) = 14515200 |
