How can I increase the timer by players in the server?

I am trying to create a timer, but I want the timer to be fair by calculating all the players and giving the appropriate time.

For example, if one player joins the game then the timer will be 30 seconds, or if two players joined then it will be 60 seconds. How do I input this "method" into my timer? Any hints would be appreciated!

wait(1)
	ftime = ftime - 1
	text.Value = "Time remaining: "..ftime
		
	local function TeamMembers(name)
		local players = {}
		for _, plr in pairs(game.Players:GetPlayers()) do
			if plr.Team and plr.Team.Name == name then
				table.insert(players, plr)
			end
		end
		return players
	end
