You can put this solution on YOUR website! the answer is:
5/18, 7/18, 1/2, 11/18
your equation looks like it is (1/6 + (1/9)*n
n goes from 1 to ........
the first term has n = 1
the second term has n = 2
etc.
when n = 1, the equation is 1/6 + 1/9 which results in 5/18
when n = 2, the equation is 1/6 + 2/9 which results in 7/18
when n = 3, the equation is 1/6 + 3/9 which results in 9/18 which results in 1/2
when n = 4, the equation is 1/6 + 4/9 which results in 11/18
if you look at your selections, the 4th selections appears to be it.
that reads:
5/18 followed by 7/18 followed by 1/2 followed by 11/18.
