NFER 11C

Post by Dawn »

Can anyone help with Q 79 of NFER paper 11C?
It is a number sequence question:

2 3 4 9 8 27 ?

My son thought that the answer should be 32 because:

2 x 4 = 8
3 x 9 = 27
and so 4 x 8 = 32

BUT the answer is 16.

Any ideas?

Thanks

Dear Dawn

The sequence is 'every other one'...

2 4 8 16

Doubling each time.
