Hi, I need help with a question regarding sequences and sums:

The upper of the two following sequences can be entered on the form of a polynomial (ie, an = degree 2 polynomial). Prove that the bottom can not be printed in the form of a degree 2 polynomial. (Hint: start by proving that the top can be entered on the form of a degree 2 polynomial).

0 1 4 9

0 1 4 10

Thanks!
