If p is a polynomial of degree 100 such that p(n) = (-1)^n (100 choose n) then the finite difference triangle of p gives you a cutout of Pascal's triangle. For example, this implies p(101) = 201 choose 101. (From the 2024 Math Prize for Girls exam.)

What do you do?
I mentor some really great students who would otherwise wouldn't be challenged by their schools.
