Moving copies unevenly

Hello everybody! I faced such a problem in Dynamo: I want to apply the formula of gradually increasing the distance in moving copies of lines. I’m trying to put the Math.Pow at a distance of movement, but the lines still move the same distance. Can someone suggest a way out?

Unsatisfactory result

Use the list as the input of Math.pow:

Thank! It worked. But in the end, the desired result is slightly different. It is necessary that the distance between copies of lines does not change so sharply and quickly. I came up with a formula, but I don’t know how to translate it. This is a formula from two lists, one of which is obtained as a result of the sum of this formula. Here’s what it looks like:
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22
22 + 7 = 29
29 + 8 = 37
37 + 9 = 46
46 + 10 = 56

It looks something like this:

Yeah, that’s how exponential functions look like…

This is a math problem rather than a dynamo problem. I’m also not really good at math, but I found the definition of this sequence here (searched for “1 2 4 7 11”): https://answers.yahoo.com/question/index?qid=20080903051936AAUvpkC

And the definition from that site works:

Thank you so much! It works, here is the result.
