Numerology does it again
I choose 1.... *3 = 3 + 3 = 6 *3 = 18, 1+8 = 9
I choose 2.... *3 = 6 + 3 = 9 *3 = 27, 2+7 = 9
I choose 3.... *3 = 9 + 3 = 12 *3=36, 3+6 = 9
I choose 4.... *3 = 12 + 3 = 15*3=45, 4+5 = 9
I choose 5.... *3 = 15 + 3 = 18*3=54, 5+4 = 9
I choose 6.... *3 = 18 + 3 = 21*3=63, 6+3 = 9
I choose 7.... *3 = 21 + 3 = 24*3=72, 7+2 = 9
I choose 8.... *3 = 24 + 3 = 27*3=81, 8+1 = 9
I choose 9.... *3 = 27 + 3 = 30*3=90, 9+0 = 9
I choose n, (n*3+3)*3 = 9n+9 = 9*(n+1), and so you get the multiplication table of 9, shifted by one place
9*2 = 18
9*3 = 27
9*4 = 36
9*5 = 45
9*6 = 54
9*7 = 63
9*8 = 72
9*9 = 81
9*10=90
Now... how on Earth did you get 4 as the result?!
