37 Fit the cubic: Un = (2n3 - 9n2 + 16n + 6)/3 for n = 1, 2, 3, ...
There are many possible answers. One possibility is Un = (2n3 - 3n2 + n + 24)/6
9.
2, which equals 54. 3, which equals 36. 4, which equals 27. 6, which equals 18. 9, which equals 12. 12, which equals 9.
12 plus 9 equals 21.

81 divided by 9 equals 9
If x=9, x=9
9-8 equals = 1
9 out of 15 equals 60%
2n2y2(2n3)(3y3)
2n3
No! It equals 15, but 9-6=3.
9 out of 36 equals 25%
9
