Answer:
First blank = 302
Second blank = 310
Third blank = 327
Explanation:
X = in
Y = out
The x is put through a function to turn into y, such as "+10" or "/2"
In this case, 50 is being added to X to turn into Y.
So for the first blank, it would be, 252 + 50, 302
So for the second blank, it would be, 260 + 50, 310
So for the third blank, it would be, 277 + 50, 327
