no

it is not an arithmetic progression

Step-by-step explanation:

Let a be the amount of air initially

Amount of air remaining after 1st pump a

-fa/4)-3a/4

Amount of air remaining after 2nd

pump- (3a/4)-(1/4)(3a/4)=9a/16

Amount of air remaining after 3rd pump

(9a/16)-(1/4)(9a/16)-27a/64

So it is not Arithmetic Progression
