Answer:
You are correct! The answer is 4
Step-by-step explanation:
Add up all the wands and divide by number of fairies in Fairyland
5+3+3+5 = 16
16/4 = 4
When the first number increases by one the second number is added by 4's. So from the first part to the second it added 4 then from the 2nd to the 3rd it skips adding 8 to then just add 12. Then from the 3rd to the 4th it skips adding 16 and adds 20. So the next set of numbers would be (4,64) because it skips adding the 24 and adds the 28.
Hope this helps and is not to confusing :)
I basically pick a couple random numbers for both variables and plug them in to see if they are true.
49/10 This is the improper way
