Answer:

11

Step-by-step explanation:

The common difference of an arith. seq. is the distance between any two adjacent members of the sequence.

The difference (increase) between -1 and 10 is +11.  

as a check, determine whether adding 11 to y = 10 results in 21.  Yes, it does.

The common difference here is 11.
