c2 arithmetic progression help

why isnt the following a a.p

One day 1 john swims 2 km and then swims the same distance on each subsequent day?
Well the distance swam each day is constant.

You could view it as an AP with d=0, though it's a bit perverse, and over complicating things.

I can't even decipher the question.

"One day 1 john swims 2km and then swims the same distance on each subsequent day?"

What's the question? How far does 5 Johns swim?

If you like being a grammar Nazi you'll have a whale of a time in the maths forum.

When you've been awake for 25 hours, using does instead of do is minor. About an hour ago I wrote "bilinear" when I was trying to write "donkey".

Sorry :tongue:

Bilinear instead of donkey? :lol:

Maybe the question is "on day one, John swims 2km, and then swims the same distance on each subsequent day"

Letting the total distance after each day being the sequence, and 2km being the difference? Just a stab in the dark.. Question might want to know how many days it'll take to reach a certain total distance..

I dont get the problem.


Clearly U1= 2km
d= 2km
Sorry guys Im using my phone and typed in the question wrong



John swims 2 km on day 1, he swims 2km on each subsequent day...why isnt this an ap.

Well the only reasonable answer I could find is that he might not swim additional distance but rather repeatadly swim the same distance -> total distance won't change, so no AP in that sense.

I still think it actually is an AP though, I guess it depends how you look on it.

Where did you have this stupid question from?
