4 5 6 7 8 9 10 11 12 13....
It is increasing by one between each number
(This could be wrong......It could be a trick!)
The sequence provided is the Fibonacci sequence, where each number is the sum of the two preceding ones. In this case, after 1, 1, 2, 3, and 5, the next number is 3 + 5, which equals 8. Therefore, the next logical number in the sequence is 8.
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8

1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
The next number is 4, followed by -2
8 -1 then +3
The next number in the sequence is 18. It's +1, +2, +3, +4, ....

4
You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.
Zero
Sequence is +4 - 3 + 5 - 2 + 6 - 1 (+1 - 1)2 6 3 8 6 12 next number 11
13, 21 - it is the Fibonacci sequence
