The sequence in the box shows the number of minutes Xavier studies math each day (20) of the week.

11, 17, 23, 29, .

Assuming the pattern continues, which function could be used to find the number of minutes, f (x), Xavier studies at the end of the 7th day?

O f(x) = 5x + 6

O f(x) = 6x + 5

O f(x) = 11 – 29

O f(x) = 29 – 11
