Answer 1

The first pattern subtracts 9 from each number, the second pattern adds 3 to each number, and the third pattern multiplies by 3.

Step-by-step explanation:

The first pattern follows the rule of subtracting 9 from each number. Starting with 74, we subtract 9 to get 65, and continue subtracting 9 from each subsequent number.

The second pattern follows the rule of adding 3 to each number. Starting with 8, we add 3 to get 11, and continue adding 3 to each subsequent number.

The third pattern follows the rule of multiplying by 3. Starting with 6, we multiply by 3 to get 18, and continue multiplying by 3 to get the next number.
