Random Power Cycle not working?

I was making a random power chooser script that cycles through power and gives a random one, but it seems to keep printing the same thing, a little help?

local Quirks = {"Explosion", "One For All", "Electrifaction", "Giantification", "Super Jump", "Super Regen"}
local RandomNumbers = {5, 10, 15}

for i = 1, #RandomNumbers do
	for i, v in pairs(Quirks) do
		print(v)
		wait()
	end
end

The hashtag Means the number of children in the table and RandomNumbers has 3 children so it will always be I = 1 , 3. Why not do

local RandomNumber = math.random(1,3)*5

That will either get 5, 10, or 15.
