Arithmetic Progression Help

[Xera_0 (ItsNotXera)]

Hello! I want to make an Arithmetic Progression that works like that:

X(a) = 1 -----> Y(a) = 0
X(b) = 2 -----> Y(b) = 0.02
X(c) = 3 -----> Y(c) = 0.04
X(d) = 4 -----> Y(d)= 0.06
X(e) = 5 -----> Y(e) = 0.08
X(f) = 6 -----> Y(f) = 0.1
X(g) = 7 -----> Y(g) = 0.12

The problem is that every X in a different script, like I can’t do Y(c) = (X(c)/100)+(X(a)/100) since X(c) and X(a) are in 2 different scripts. Also, I want this to be automatic, that means that if the script has X’s value, it gets Y’s value automatically without me writing anything.
Thanks

Nevermind, I found something really easy that works the same

local X = 4/100 -- Y should be 0.06
local X1 = X - 2/100

local Y = X + X1
