assuming the value stars at 1, I think I'd go with

generateSequence(1) { (it * 2).takeIf { it < 1000 } }.forEach { // something here }

menegatti: Shouldn't that be it < 1000?

[menegatti]

or takeUnless?

That works too

[menegatti]

but you're right

thanks, that's a good a idea. i think it can be even better:
for (i in generateSequence(1) { it *2 }.takeWhile { it <1000 })
