Answer 1

Answer: -5

Explanation:

Answer 2

Answer: 5

Explanation:

The formula for calculating common difference is given by :

`t_(2)` -
`t_(1)` =
`t_(3)` -
`t_(2)` =
`t_(4)` -
`t_(3)`

Where
`t_(1),t_(2)` are the terms given .

from the sequence given :

`t_(1)` = 105

`t_(2)` = 110

`t_(3)` = 115

`t_(4)` = 120

Therefore : common difference will be

110 - 105 = 5

115 - 110 = 5

120 - 115 = 5

Therefore , 5 is the common difference
