Solved I need some math please!

[Xagul]

I need a(couple) math formula(s) to do math on the value of "i".

What I need is as follows:
if i = this then x = should equal this and y = should equal this

And here are the values I need it to come out to:
i = 1 | x = 1 | y = 2
i = 2 | x = 3 | y = 4
i = 3 | x = 5 | y = 6
i = 4 | x = 7 | y = 8
i = 5 | x = 9 | y = 10
i = 6 | x = 11 | y = 12
i = 7 | x = 13 | y = 14
i = 8 | x = 15 | y = 16

 

[imkingran]

x = i * 2 - 1
y = i * 2

Is that what you meant?

So you want a function that: for i = index prints an even number and an even number + 1(aka odd number)?

Damn that was quick. Thank you good sirs! [̲̅$̲̅(̲̅ ͡° ͜ʖ ͡°̲̅)̲̅$̲̅]

if i % 2 == 0 then
-- even
else
-- odd
end

for i = 0, 16 do
    if i % 2 == 0 then
        print(i)
    end
end

0
2
4
6
8
10
12
14
16
