Question

the difference of fare for each kilometer is salle 1.c,
of the air remaining
The amount of air present in a cylinder when a vacuum pump removes
in the cylinder at a time.
linder is x.​

Answer 1

Answer:

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 –(a/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 the series is like

a,3a/4,9a/4,27a/64……..

Difference Ist and second term=-a/4

Difference between Second and Third term= -3a/16

So difference is not constant

So it is not Arithmetic Progression
