How do i write s={1, 2, 3, 6, 9, 18} in set-builder notation?

1 - (1/3 x 2) = 4 inches (The equation may not be exactly correct but the answer of 4 inches is.)

Step-by-step explanation:

The beetle has 4 inches, 2 of which it already had before hand.

4 - 2 = 2

1/3 distance that the ant is would be 2 inches, so then you would find the number that 2 is one third of.

1/3 = 2/6

1 - 2/6 = 4/6

The ant is 4 inches below ground level.
