Can you solve this?

The guy gives three numbers that follow a rule: 2, 4, 8.

He then asks people to give him other numbers, and to see if they (the newly-given numbers) follow the rule.

Video gives an interesting perspective on looking at things...

Could be a bit of fun there, as we don't quite know what the "rule" is...

The obvious thing that jumps out at me is that each number is double the previous one. 2, 2+2=4, 4+4=8, so my first guess would be 16, 32, 64 and so on.

ETA: Halfway thru the video... and I think the rule he's actually using is each number is larger than the previous one?

The rule I've heard is each number spelled out has one more letter than the previous.

Two (three letters)
Four (four)
Eight (five)
