How to write negative loop in ruby like for(i=index; i >= 0; i --)

Question

How can I write a loop in Ruby that counts down, similar to the following C-style for loop?

for (i = 25; i >= 0; i--) { 
    print i;
}

Print reverse array elements:

nummarray = [3,4,7,3,6,8]

(numarray.length-1).downto(0){ |i| print numarray[i] }
