Answer 1

Answer: -5

Step-by-step explanation:

Answer 2

Answer: 5

Step-by-step 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
