This is a 4 step sequence , starting with the number 1.
1) Double the number
2) Add 2
3) Subtract 1
4) Return to step 1) and repeat.
1 x 2 = 2 ; 2 + 2 = 4 ; 4 - 1 = 3 ; ..........7 x 2 = 14 ; 14 + 2 = 16.
Then the next number is generated by Step 3).. 16 - 1 = 15
The next numbers in the sequence are... 16, then 88.
15
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
16 is the next squared number.
The series 1318162119 appears to be a sequence where each number is formed by concatenating the first few even numbers. The pattern is: 2 (2), 4 (4), 6 (6), 8 (8), 10 (10), 12 (12), 14 (14), and 16 (16). Following this pattern, the next even number is 18, which would be represented as "18" in the series. Thus, the next number in the series is 20, resulting in the next sequence being 131816211920.
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
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
16 is the next squared number.
The next number in the sequence 2, 4, 16, 64 is 256.
are you sure it is not1 2 3 6 8 7 14 16because that sequence doubles for the first one, then adds two for the next number, then subtracts one for the third, then repeats. So the next number is 15.
