Answer 2

Answer:

Step-by-step explanation:

If the common difference between any two consecutive numbers is equal then the series is an A.P.

1.  2, 4, 8, 16...

---> here Common difference

$d = a_{2} - a_{1} = 4 - 2 = 2\\d = a_{3} - a_{2} = 8 - 4 = 4$

---> here Common difference  is not equal hence this is not an A.P.

Similarly for all remains.
