Question

what is the common difference of an A.P. -307, -305, -303, -301​

Answer 1

Answer:

common difference is 2

Step-by-step explanation:

In an AP, you can always find out the common difference by subtracting the preceding the term from the succeeding one.

In this AP, the common difference can be found out in this way,

-305-(-307)=-305+307=2

You can check it for other terms as well, like,

-303-(-305)=-303+305=2

Hope this helps.
