Mateo uses a rule to write a number pattern. The first number in the pattern is 7. The rest of the numbers in the pattern are odd. Which sentences could be true about Mateo's pattern? Choose all the correct numbers.

• The rule is to subtract I because the difference between two odd numbers is always odd.

• The rule is to add 5 because the sum of two odd numbers is always odd.
