This is why I hate questions like this on IQ tests etc.
If you ask someone to continue the sequence
1,2,3,...
most people would answer 4, but 100 is an equally valid answer, because the formula
16n^3 - 96n^2 + 177n - 96
generates the sequence
1,2,3,100
It's always possible to fit a polynom to any sequence of numbers.
