The possible combinations are for the values of l when n = 2 is two values 0,1 and ml is -1,0,1
The n is the principal quantum number
l is the azimuthal quantum number
ml is the magnetic quantum number.
The formula to find the azimuthal quantum number is
l = 0,1,2,3 .......n-1
If n = 2, the azimuthal quantum number,
l = 0, 1
Then, the ml can be found using the formula,
ml = 2l +1
For l = 0 , ml = 2(0) + 1
= 1
Therefore, ml will have only one value, which is 0
For l =1 , ml = 2(1) + 1
= 3
Therefore, the ml will have three values, they are -1,0,1
