For the multiples of 3 you just divide the number by three and +1 to one
and -1 from one. For example 15 divided by 3 = 5. 5+1=6 and 5-1 4.
4+5+6=15

That you can not complete any of the powers of 2. e.g. 1,2,4,8,16,32,64...
You can also complete every odd number by using 2 numbers with a method like
1+2=3, 2+3=5, 3+4=7... 11+12=23
For every odd number add 1 and half it. Then subtract 1 from one and
You can make every multiple of three using 3 numbers 2+3+4=9
you have your answer. 15+1=16 half =8. 8-1=7. 7=8 15.

Are there any other patterns?
Can we explore the powers of two farther?
And is it the same for any other powers?
Is there a solution to solve certain
Numbers (for example every other even
Number )?
