The first number in a pattern is 10. The rule is to add 9.

Select the true statement.

The numbers in the pattern switch between even and odd.

All of the numbers in the pattern are divisible by 5.

The first number in the pattern is 10. Use the rule to find some more numbers in the pattern.

Start at 10 and add 9. Then, keep adding 9 to find more numbers in the pattern.

This is the pattern:

10, 19, 28, 37, ...

Now, look at the first statement.

green checkmark, The numbers in the pattern switch between even and odd.

See if this is true for the numbers you found.

10, 19, 28, 37, ...

The numbers switch between even and odd.

If you keep adding 9, the numbers will still switch between even and odd. So, the first statement is

true.

Now, look at the second statement.

red X symbol, All of the numbers in the pattern are divisible by 5.

A number is divisible by 5 if it can be divided by 5 with no remainder.

19, 28, and 37 are not divisible by 5. So, the second statement is not

true.
