Generate a increasing increment array

Hi,

I was wondering how to generate array as follow

 1 4 9 16 25

As you can see, the differences between them is

 3 5 7 9

of increasing order. I was wondering how to do that without using any loop?

Thanks Andy

1 + cumsum(3:2:9)

Not sure what the rule is (actually I guess Walter figured it out since you accepted it), but here's another way:

>> v = (1:5).^2
