    A tough logarithmic scale question

    Hello all,

    I have a question regarding logarithmic scales. Suppose I have an initial number (lets just say its 10) and a number I want to get to using logarithmic steps (lets say its 20).

    If I have an order of magnitude in mind and a number of steps in mind, is there a general way of finding out what my first step should be? For example, if I want to get from a to b using 10 steps where each step is 3 times larger than the last, what should my first step be?

    Thank you all very much for the help,

    Nick
