    How do you find the function that describes this sequence?

    Ok I figured out where the 390 comes from. The length of each iteration of the algorithm is 390(from 91 to 481). So it's the difference between the 1st number in the sequence and the 15th. Yet I know that the mod operator calculates the remainder. I can't yet understand how it works in...

    How do you find the function that describes this sequence?

    It works! The solution seems so simple it's almost embarrassing. But before I say anything else, THANK YOU NORWEGIAN! I'm still fiddling with a calculator and pen and paper but I simply cannot figure out how you got it. If I had to guess I'd say it's got something to do with factors or...

    How do you find the function that describes this sequence?

    The sequence is: 91,93,95,141,143,145,147,243,245,247,249,295,297,2 99,481,483,485,... Thank you for pointing out the need for clarification I was very unclear the way I described it and yes the starting point was totally wrong it's not 1 but 91. I hope that helps a bit, if it does I...

    How do you find the function that describes this sequence?

    Yes there is a pattern for the gaps I included it in the algorithm I showed but it's not pseudocode so i don't know if it's understandable but close to the python language. If you take 141 and subtract 95 you get 46. So 46 is the gap between the third number in the sequence and the fourth...

    How do you find the function that describes this sequence?

    Thank you for the suggestion it showed me the correct way to display a sequence and it was stupid the way I showed it. I search for it on that site but it picked up no results.

    How do you find the function that describes this sequence?

    I'm not and expert in math and have only high school level math which has mostly faded from memory. I've been searching the net to see if there is an algorithm or something to derive a function from a given input and output sequence of numbers. I'm guessing you just have to do it by hand as one...
