Hope this helps :)

t(n) = n2 + 5n - 1
7n
2n^2-1
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.

t(n) = n2 + 5n - 1
-n2+2n+49

2n^2-1
(Term)n = 59 - 2n
There are infinitely many possible answers. the simplest polynomial is Un = -n4 + 12n3 - 47n2 + 78n - 41
13/49 is in its lowest terms

tn = 4 + (3/2) n (n - 1) = (3n2 - 3n + 8) ÷ 2
It is 2849/1.
