Answer 1

The common difference is -6.

Because,
14 - 6 = 8
8 - 6 = 2
2 - 6 = -4
-4 - 6 =-10

Answer 2

Answer: The common difference= -6

Explanation:

Here in the given sequence the first term=
`a_1=14`

The second term=
`a_2=8`

The third term=
`a_3=2`

The fourth term=
`a_4=-4`

The fifth term=
`a_5=-10`

The difference between the consecutive terms=
`d=a_2-a_1=8-14=-6`

`d=a_3-a_2=2-8=-6`

`d=a_4-a_3=-4-6=-6`

`d=a_5-a_4=-10-(-4)=-6`

hence the common difference= -6
