Help with those numbers

[Fishermens]

The subject is seeing patterns in numbers.
2-4-6-8 etc.
1-2-3-5-8-13 etc.
Here we go...

2-10-4-8-40-16-6-?

Could any one help me out here?

I'm studying for a upcoming assessment.
Did 100 questions already with no problems so far. until now...

A cold beer to the first to give me the clue!

Cheers!

14 I think.

First they multiply by 4, skipping 2 numbers, then they add 4.
2x4 = 8
10x4 = 40
4x4 = 16
The sequence finished now, so they started adding 4.
2+4 = 6
10+4 = 14...

I do not know the answer but this would be my guess.

Hey buddy,

2-10-4-8-40-16-6-

A long shot, but could it be...

Difference between 10 and 2 is 8
50% of 8 is 4
Difference between 8 and 40 is 32
50% of 32 is 16

I would need to see the next combinations offered to see if that is the pattern?

I could be completely wrong of course..

I see batches of three where one batch is a multiple of the first: 8-40-16 is 4x(2-10-4).

Since the first number of the third batch is 3x2, I think the third batch would be 3x(2-10-4)= 6-30-12. Which makes sense with gbotley's reasoning.

I also got 12, I had the same reasoning as Amidoo.

I've always gotten tripped up by sequences that aren't fully mathematical in nature, but in 'batches' as he says. You're allowed to evalute the chunks individually.

that said - Don't sweat it. You're not at all supposed to be a genius :)

Argh.. I see... So it should/could be 2-10-4-8-40-16-6-30-12, right?

Thank you so much. Think my wife will appreciate it... :)
