Answer:
times 3
Explanation:
ok so this is how I do it, I recommend it!
Look out the out number in the first number: 6
Ask yourself how to get from 6 to 2???......divided by 3 ofc!
Ok so then we see 4 and we multiply by 3=12
21 divided by 3 is 7! Rule right again!
27 divided by 3 is 9! Yay we did it!
Hope this helps :>
