Answer:

-7

Step-by-step explanation:

arithmetic sequences are consistant sequences by adding or subtracting a constant term, in this case to get from -6 to -13, you subtract 7. And to get from -13 to -20 you subtract 7 again. The next number in the sequence would be -27 as -20-7= -27

Hope this helps!

Common difference = 2nd term - first term

= -13-(-6)

= -13+6

Answer:

The value of the unit rate is 8

Step-by-step explanation:

we know that
