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
17?
13, 14, 16 - the numbers increase by 1 then 2 each time
They are square numbers
14 and 16 go into infinite amount of numbers.
1, 4,9, 16, 25, 36,49 this is the next three sequence po
The next numbers in the sequence are... 16, then 88.
Based on the sample you have provided, I see that 4 numbers, counting by 2 from 12 to 18, form a repeating sequence. I would expect that the next 4 numbers in this series would again be 12, 14 16, and 18.

The solution depends on how many numbers are missing and where they were. If there is only one, If it is between 4 and -5 then -0.5 If it is between -5 and -10 then -8 If it is between -10 and -16 then -13 Of course, the answer would be different if there were more than one number missing.
6+10=16 and 16-2=14
They are: 14+15+16 = 45
25 36 49 64 81 100 121 144
