This question was answered not that long ago.

I expect that you mean the numbers 1,2,3,4,5,6,7,8,and 9

What have you done already towards solving this ?

Have you worked out which triples add to a multiple of 3?

i worked out that if i have the numbers in ascending/descending order, it will be divisible by three (because x-1 + x + x+1 would be equal to 3x)

im not sure how to use that information to work out the total number though (or if there are other ways to place them).

 

I would love some guidance :)

First I will state that i haven ot attempted to work this out.

Someone else answered last time.

 

So you have worked out that these cannot be together

1,2,3

2,3,4

3,4,5

4,5,6

5,6,7

6,7,8

7,8,9,

8,9,1

9,1,2

 

Mmm

There are lots of others too.  like 3,6,9 etc

 

This is really tricky.

Seems you will be accused of cheating....

I'd give you some guidence if I had any but I really don't

 

I'd play around some more with when trippled can or cannot go together but I do not have any brainwaves.
