2n^2-1
nth term of 1 7 17 31.....
+9
7n
3n2 + 1Hope this helps :)
The next number in the sequence is a multiple of the number times seven, so the nth term would be 7n . 71 = 7 72 = 49 73 = 343 74 = 2,401 75 = 16,807 76 = 117,649 etc.
The difference between successive terms is 8 tn = 8n + 9 or 8(n+1)+1 where n = 1,2,3,...
+9
-n2+2n+49
7n
There are infinitely many possible answers. the simplest polynomial is Un = -n4 + 12n3 - 47n2 + 78n - 41
(Term)n = 59 - 2n
3n2 + 1Hope this helps :)
