My nine yo son has a little pattern problem that I was not able to solve. Hopefully you can help me..
What is the missing number?
(2 , 18) (3 , 12) (4 , 9) (6 , ?)
a. 8
b. 7
c. 6
d. 5
Thanks in advance.
This sort of question has an infinite number of possible solutions.
At your son's level though it is probably a quite simple one. You might want to consider what you get when you multiply the two numbers in each set of brackets.
