it increases 3° each hour

3*2= 6

6° after 2 hours

3*3= 9

9° after 3 hours

3*6= 18

18° after 6 hours
6, 9, then 18. Just add 3 every time because it is asking how much it increases. For the first one you multiply it by 2 (2h) which got 6, for the second you multiply it by 3 (3h), and for the last one you multiply it by 6 (6h) which got 18.
