Thanks guys, you are right :)

Except last time the meaning was made clear, this time it was not :)

Não sei se é isso que está perguntando.

\(\frac{1}{4}\;\times\;60\;=15\)

Do you understand now nerdiest? 

You are a good student here and you never should be worried about saying clearly when you do, or do not fully understand.

I put an emphasis on the work 'clearly'

Thanks to the three of you who have helped here :)

I have just looked at your posting history.

You are only hear to collect answers and on occasion you give abuse.

You have never thanks anyone for trying to help you nor have your ever interacted properly with an answerer. 

You have however abused an answer once.

So how about you just go away?

hint

\(\displaystyle \boxed{r=\frac{a_n}{a_{n-1}}=\frac{a_2}{a_{1}}=\frac{a_3}{a_{2}}=etc}\)

The meaning of this question is not clear to me.

Is 1d41 a base 8 number? 

What have you done for yourself?

Thank your for resonding.

12 is a small number, I challenge you to list them.

I can se no relevance at all of 5C2. Perhaps you would like to explain?

I didn't get 12

What 12 did you get?

Thanks Builderboi.

Here is another way of looking at it.

Since it is a equilateral triangle, the point is just as likely to be closer to A as it is to be closer to B

what does that tell you.
