Lua：如何将许多数字转换为一个变量

local a= >3500
local b=
local c= <3700

我不知道如何将中间的200个数字转换为变量 b

    lives=1

while lives > 0 do

math.randomseed(os.time())
local randomNumber1 = math.random(7200)
local randomNumber = math.random(randomNumber1, 7200)

print("欢迎来到轮盘赌游戏！")

local a= >3500
local b=
local c= <3700

local number1 = io.read()
local number1 = tonumber(number1)

if
    number1== a
    and randomNumber == a then
    print("你赢了！")
    print("数字是 "..randomNumber..)

else if
    number1 == b
    and randomNumber == b then
    print("你赢了！")
    print("数字是 "..randomNumber..)

else if
    number1 == c
    and randomNumber == c then
    print("你赢了！")
    print("数字是 "..randomNumber..)

else
    print("你输了")
    print("数字是 "..randomNumber..)

io.read()

lives=lives-1

end
