Ms. Sue
Please see my answer to your other problem. It has a good clue about the answer to this problem.

shy
yes i think i got would the number pattern be 2???
Ms. Sue
If you multiply two odd numbers, would you expect the product to be odd or even?

Ms. Sue
Right.

shy
i meant the answer to my other problem that i got was the #2 number pattern.
shy
so i know that i would use the #5 number pattern for one answer but i gotta use two number patterns so would 9 be the 2nd number pattern?
Ms. Sue
The digits of all multiples of 9 add up to 9.

18, 27, 36, 45, etc.
