8-n
It could be 37. Use Un = (n4 - 6n3 + 18n2 - 18n + 168)/24 with n = 6
There are infinitely many possible answers. A simple polynomial is Un = (5n3 - 18n2 - 11n + 72)/6 for n = 1, 2, 3, ...
24 x 6 = 144 + 8 = 152
The GCF of 8 and 144 is 8.
152
No, but 8 is a multiple of 144.
8 x 144 = 1152
-8*18 = -144
