Scala Random Number

Ok, I understand how to implement a random number generator in Scala and how to set the upper bound for the random number being generated, but I am confused as how to change the lower bound. For example:

    var computerGuess= scala.util.Random
    var higher=100
    var computerGuessInt=computerGuess.nextInt(higher)

will let the computer generate a random number from 0 to 100.

But I want to change the lower bound to be, say 29 so that the computer could pick a random number from 29 to 100. How can I do this?
