17?
It would be 16. The sequence is doubling pairs. 3 and 4 go on to be 6 and 8. 6 and 8 would go on to be 12 and 16. 12 and 16 would go on to be 24 and 32, and so on.
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
16
It is: 34
A single number, such as 4642142824816 does not constitute a sequence.
The 40th number in the sequence will be 40 x 4, or 160.Reasoning:Because the sequence is multiples of 4.The 1st number in the sequence is 1 x 4, or 4.The 2nd number in the sequence is 2 x 4, or 8...The 4th number in the sequence is 4 x 4, or 16...The 17th number in the sequence is 17 x 4, or 68
16
My guess: 2.5

It is a number sequence.
The next number in the sequence 2, 4, 16, 64 is 256.
The next number in this sequence should be 33.
