There are infinitely many possible answers.
One is
Un = (n5 - 10n4 + 55n3 - 110n2 + 184n - 120)/120 for n = 1, 2, 3, ...
Another possible answer is
Un = 2n-1 + 1 for n = 1, 2, 3, ...
Which one of the two? And if you choose one over the other, why did you pick that one and not the other? And why stick to only these two when there are infinitely many to choose from?

What is the pattern rule for this pattern 3-4-8-17-33?
After the initial number 3, the next number is generated by adding the square of numbers increasing by one at each step and starting with 12. 3 + 12 = 4 4 + 22 = 8 8 + 32 = 17 17 + 42 = 33....and so on The series formula is U(n) = n3/3 - n2/2 + n/6 + 3, which can also be written as :- 3 + n/6(2n2 - 3n + 1) = 3 +n/6(2n - 1)(n - 1)
