Answer 1

Answer:

7

Step-by-step explanation:

a1 = -1

a2 = -8

d1 = x

d2 = x

T4 = a + (3) d

Difference between 4th terms = a1+3d - (a2+3d)

                                                    = a1-a2 +3d-3d

                                                    = a1-a2 = -1-(-8) = 7

I hope you mark my answer as the brainliest.
