Answer 2

The value of n is 12. We can decipher this, as we can know the value of n must be less than 24. We can figure out n in a few ways. First we can divide 24 by 2, which will give you 12. We can also go through the numbers and multiply them by two, to determine which will give you 24. 2x2 =4. 3x2= 6 4x2= 8 5x2= 10 6x2= 12 7x2= 14 8x2= 16 9x2= 18 10x2= 20 11x2= 22 12x2= 24
