We need to find whether the situation given below makes an arithmetic progression and why?
I hope you can understand what I'm asking. please explain to me the answer
Yes it does you could even make the arithmetic equation of this. Say you have a volume of 5 (units) in the cylinder...
if you keep taking down the volume by 1/4 then it decreases by a common amount each time.
l'll even write out a sequence.
5, 19/4, 18/4, 17/4...
l'm sure you can figure the arithmetic for this, if not, let me know c:
Note that this forms a geometric progression, not an arithmetic one.....the amount that reamins each time is (/3/4) of the previous amount.....a common ratio...
We start with 5 units.....removing 1/4 of the air means that 5(3/4) = 15/4 units remain
Then....removing (1/4) of this means that (15/4)(3/4) = 45/16 units remain....etc.
