Someone explain how to do this dont need just an answer but explain as well

6.5 goes in the first box and 5.5 goes in the second box.

Explanation for first box: 13+2 is 15 and half of 15 is 7.5 so you need to take 13 and subtract 7.5. Once you do that, you end up with 6.5

Explanation for second box: (The negative 7 doesn't matter because you want the absolute value) 18+7 is 25 and half of 25 is 12.5. 18-12.5 is 5.5 so the answer would be 5.5

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
