Hello !!

For you answer this question, you only need make use of this method below. See the resolution.

M(3) = 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33...

With this information, we have :

24 + 27 + 30

= 20 + 20 + 30 + (7 + 4)

= 40 + 30 + (7 + 4)

= 70 + 11

= 81

Therefore, 30 is the largest number.

I hope I have collaborated !
