Here's how you get from one number to the next: if the current number is odd, multiply by three, then add one. If it's even, divide by two.
Sunrise by Planet: East or West
Enter '27', would you?
Since it's odd, multiply by 3 then add 1. What do you get?
82 is even, so divide by 2. Now what?
Odd! 41*3 + 1 = ?
Even! 124 ÷ 2 = ?
Even! 62 ÷ 2 = ?
31*3 + 1 = ?
(You were at 94.) Get it?

(214) Do they bother you?
(107) Would you believe I feel the same?
(322) Is there a way to turn them off?
(484) You know what?
(242) I'm just gonna ignore them. ?
(121) If you'll kindly keep your eyes?
(364) pointed at the entry box,?
(182) you'll have no trouble scrolling?

(395) That bad news you're noticing now:?
(1186) these numbers get pretty big!?
(593) The good news is that, eventually?

(890) they'll calm down.?
(1336) Ooh, just one shy of greatness.?
(668) The neighbor of the beast!?
(334) 334.... I got nothing.?

(1438) Whew! Good work.?
(719) Uh oh.?
(2158) Spoiler: this part hurts.?
(1079) Just squeeze my hand if you get scared.?
(3238) Think happy thoughts.?
(1619) Or just think about arithmetic.?
(4858) Interesting fact!?
(2429) The number you're about to type RIGHT NOW?
(7288) is (was) merely the second largest.?

(70) He noticed that wherever he started,?
(35) eventually he'd get to one particular pattern.?
(106) For ages people have tried to prove?
(53) that this always happens.?
(160) And indeed, as far as we can tell, it does.?
(80) (Though sometimes it takes a long time.)?
