Fit a function in the form ax^3 + bx^2 + cx + d to a local minimum and maximum at (4,7) and (6,-2)

I know this involves a system of equations and substitution but I have no idea how to do it. Thanks!

I'm a visual artist and I make process drawings using a simple, 3 digit code. the code can be very short or very long, but the number of units is always set - if you take the series of lengths of the code, you get this:
3, 7, 23, 87, etc.
i can see the relationship between these numbers (the value of the new number equals that of the previous one, plus 4 to the power of the ordinal value of the previous one), but I want to know whether this is sequence that comes up anywhere else... and how can I express this in a proper way?

You can add, subtract, multiply, divide or use powers eg 4 to the power of 4. I have got every number up to 20 except 19. You can also stick digits together e.g 44 or 444.
