Um, your sum should be 4.

Step-by-step explanation: The sum of an infinite geometric series can be found using the formula where a is the first term and r is the ratio between the successive terms.

For , find the first term in the series by substituting in the lower bound and simplifying: a=1.

For r, find the ratio of successive terms by plugging into the formula and simplifying: .

For 1–r, substitute the values of the ratio and first term into the sum formula: ; ∴, your sum should be 4.

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.

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
