You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.
5
It could be 34, if you use the position to value rule Un = (-9n4 + 106n3 - 429n2 + 692n - 348)/12 for n = 1, 2, 3, ...
The next number is 4, followed by -2
1+1=2 1+2=3 2+3=5 ... 8+13=21
38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.
The next term is -2.

It could be 34, if you use the position to value rule Un = (-9n4 + 106n3 - 429n2 + 692n - 348)/12 for n = 1, 2, 3, ...
The next number is 0. The position to value rule is Un = (-n4 + 9n3 - 17n2 - 15n + 54)/6 for n = 1, 2, 3, ...

The next number is 4, followed by -2
The answer is 8 because 1+1=2, 1+2=3, 2+3=5,and 3+5=8.
