-3 -(-7) = -3+7 = 4

1-(-3) =1+3=4

5-1 =4

Arithmetic the common difference is 4


-17 --9 = -17+9 = -8

-26 --17 = -26 +17 =9

Not arithmetic


8-19 = -11

-3-8 =-11

-14--3 =-14+3=-11

Arithmetic the common difference is -11

Answer:

1 is B, 2 is A, 3 is B

Step-by-step explanation:

I had these questions and got this correct

I tried adding/subtracting each number in the sequences by the givin choices. (ie.: -7+4=-3+4=1+4=5, etc. )(19-11=8-11=-3-11=-14, etc.)

Common difference is the pattern in which  the sequence increases/decreases. Therefore, 1)B, 2)A, 3)B
