Can someone help me with a loop problem?

I am trying to make a loop run 198 times. Every 20th time it counts, I want it to turn the bool value of 'on' to 'true'. After every 24th time it counts, I want 'on' to be 'false'. Does that make sense? I don't know how I would write this... Maybe with a for loop. Can someone help me out?

I think this is what you want. btw this is not a request site and I am doing this out of the kindness of my heart.

local bool = nil

for i = 1,198 do
if i%20 == 0 then
bool = true
elseif i%24 == 0 then
bool = false
end
end

Enjoy!
