How do I calculate a ratio from 2 numbers and return an equivalent list of about 1000

[ndc85430]

{1: 8978, 2: 17956, 3: 26934, 4: 35912, 5: 44890, 6: 53868, 7: 62846, 8: 71824, 9: 80802}
For instance, I want to use some unknown input for the program to find this ratio pair ( 5: 44890) and while going through a series of numbers in the dictionary during the codes processing; I would like it to print (44890) at the conclusion of its processing.

I don't really understand what you're trying to do. How does the input relate to what you're trying to find? Imagine you didn't have a computer and had this collection of values written down on paper. How would you find the one you want? With quite small problems like this, you should be trying to figure out the steps in getting to the solution. Code will naturally follow from those (assuming you know the right code elements to implement your solution, but you need to start at finding the solution first).
