Experts/ace where do i put the dots?

1st dot (0,48) then each dot after than subtract 6 from the Y and add 1 to the x

2nd dot (1,42)

3rd dot (2,36)

etc.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

probably .5

i can on others if necessary.
