I've been looking for this anywhere I can but I'm not sure how I would even search for it since it is more of a question. If you had 10 numbers and the first number was say 1.978 and the last number was 19.335 is there a function to produce the correct 100th number(if of cousre you had a way to in fact check or knew the answer ahead of time)? I've tried using log but it obviously just goes from 1.978 to 19.78. Am I missing something to logs that can account for a run of numbers that increases or decreases at a non uniform rate? I see why it doesnt work but I honestly just dont know enough yet to see how to correct for this.

Its hard to ask this question on wikipedia or math world so what little the search returns is mostly about logs. It seems that this would be quite more difficult than just using logarithms since at each step the difference isnt the same for the last number. I'm getting frustrated but I'm still learning. It seems like the problems that hold you down for a while teach you the most so I guess its ok.

Thanks for any help,
