The next in the first pattern is 15.
The next in the second pattern would be 3.
The next in the third pattern would be 32.
Step-by-step explanation:
In the first pattern, you can notice that the terms keep going up by 3. As a result, the next one is 3 higher (12 + 3 = 15)
In the second pattern, the next number is always half of the number before it. (6 * 1/2 = 3)
The last pattern shows each number being 10 less than the one before it. (42 - 10 = 32)
