A three-character code uses the letters D and Q. Either of the letters may be repeated.

Find the probability of a code with exactly two D’s. (Hints: Use a list or a tree-diagram to help you. Also, notice the language. They only care about getting exactly two D's. They do not care about the order of the letters.)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
