(4x - 1)(3x + 5)
Try different combinations of the front number's factors with combinations of the last number's factors. The FOIL until you find one that works.
The first term is -16, so we have
... a[1] = -16
Each term is -1/4 of the one before it, so the recursive rule is
... a[n+1] = (-1/4)a[n]
