Sorry. It's not clear. Plz tell me if there is 12 3/8in?
Geometric sequences go up due to a common ratio. Here the common ratio can be worked out by dividing a term by its previous term e.g term 2 divided by term 1.

Therefore the common ratio is 6.
Step-by-step explanation:
so, you don't know what a division is for ?
it is to ask things like "how often does one number fit into another number", or "how big will each piece be, if I split something into a certain number of equally sized pieces ?".
this is what we need here.
8 pizzas for $131.36. and each pizza costs the same. you see how that connects to what I just described above ?
to find how much each pizza cost, we need to divide the total price by 8, to find the size (= here the price) of each of the equally big parts of the total price.
131.36 / 8 = $16.42
Answer:
1.75 or 1 3/4 pieces each
Step-by-step explanation:
