Step-by-step explanation:

First method

difference between first term of the both series is ans i.e common difference between this Aps is=(-1+8)=7

2nd method

4th term of the first AP =-1+3D

4th term of the 2nd ap is= -8+3D

The difference between their 4th term=(-1+3D)-(-8+3D)=7

where D=common difference of first AP=common difference of 2nd Ap.
