How do I make the second 'I' 2 less than the first??

local children = workspace.Track:GetChildren()
for i = 1, #children do 
local child = children[i]
print("local tween"..i.." = ts:Create(part2,Tweeninf,move"..i-2..")")
end

Basically I want the I after the move part to be two less than the I after the tween part but this won't work :/ Any idea how to make it work??

Just make a new variable

local children = workspace.Track:GetChildren()
    for i = 1, #children do 
        local child = children[i]
        new_i = i - 2
        print("local tween"..i.." = ts:Create(part2,Tweeninf,move"..new_i..")")
end
