Question

what is the common difference of the AP formed by even number​

Answer 1

Answer:

2

Explaination

Since all the numbers in the ap are even, then common difference will also be even(eg 12,14,16. in this case d is 2, in 12,16,20 d is 2)

So according to me the possible common differences are

2,4,6,8,10,12 and all other even numbers
