Answer:
Rule: multiply by two
100 = 200
n = 2n
Step-by-step explanation:
First pay attention to the information given to you. 1 goes to 2, 2 to 4, 3 to 6, and 4 to 8. You need to find the rule, or how exactly the input goes into the output. Let's start with 1 x 2 = 2. That would fit for the first one. So we will try that for the next one. 2 x 2 = 4. The rule of multiplying by two works for the second one too. Now we do the third. 3 x 2 = 6. Works again. Next, 4 x 2 = 8. So the rule of multiplying by 2 works for all of the given information.
Now that we have the rule, we can use it to find the missing information. 100 x 2 = 200. So that's your first answer. The second one is a little more tricky if you think about it too hard. The simple answer is 2n. Because n is only a variable and not a real number, it can't be completely multiplied like the rest. It becomes 2n or, 2 times n.
I hope this helped :)
