Answer 3

...Yes it does. :) What dont you understand?

Answer 4

thats correct @Confusionist , but wouldn't you want to explain the asker how you got it ?

Answer 5

this question i got in business maths... and its correct .

Answer 6

I definitely believe Confusionist, but I don't understand this type of math so I'd love to hear it explained!

@Confusionist I thought an arithmetic mean meant to add 5 and 25 and divide by the number of terms (in this case 2) and I'm used to there only being one arithmetic mean, not three, so please enlighten me =D

Answer 7

basically we use the fact that
Arithmetic Mean between A and B is (A+B)/2

Answer 8

ok I'm with you so far

Answer 9

that would be the 2nd AM((5+25)/2)between 5 and 25

which is 15
now we need Am between
5 and 15
(5+15)/2
which is 10
and so on

Answer 10

we can add as many AM's in between as we require :)

Answer 11

Ah, you've got it, hartnn? Sorry, I was getting a coffee

Answer 12

oh haha, no problem :)

Answer 13

ah I see.
I imagine it always has to be an odd number of AM's?

Answer 14

How did you get 20 and 10?
