Let f be a differentiable function such that f(3) = 2 and f'(3) = 5. If the tangent line to the graph of f at x = 3 is used to find an approximation to a zero of f, that approximation is? So confused

Is there an easy way to find a pattern in a function table, so you can write a function rule? Or is there no easy way, you have to keep on guessing, by observing the table?
