The simplest sequence appears to be 15
1*2=2
2+2=4
4-1=3
3*2=6
6+2=8
8-1=7
7*2=14
14+2=16
16-1=15
Multiply by 2
Add 2
Subtract 1
Repeat
The next numbers in the sequence are... 16, then 88.
15
16 is the next squared number.
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
The next number in the sequence is... 64
A single number, such as 4642142824816 does not constitute a sequence.
The next numbers in the sequence are... 16, then 88.

17?
From the given sequence, the pattern appears to be 47-42=4, 42/3=14, 14*2=28, 28-4=24, 24/3=8, 8*2=16 and therefore the next number will be 16-4=12.
15
The next number in the sequence is 15 - the sequence goes x2, +2, -1
15
16 is the next squared number.
The next number in the sequence 2, 4, 16, 64 is 256.
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
