Answer:
2=4, 3=6, 4=8, 5=10 I'm pretty sure.
Explanation:
If two is equal to four, then that means for every number multiply by two because two times two is four. So you would just multiply all of them by two. But it also says at the bottom that y=8 so that means you would multiply all of the numbers my two, then multiply that number by two as well because in the example it states that "Y= 4*2" The "*" means cubed so you multiply the original number by two. Hope this helped!!
