V=4/3 πr^3would be the formula
Answer:

Step-by-step explanation:
<u>Recursive sequence
</u>
In a recursive sequence formula, each term
is computed as a function of one or more previous terms. In the formula

n is the number of the term we want to calculate. If n=8, then the formula becomes

We can see
is the previous term. It means we need
to be able to compute
. But we also need
to compute
and so on until some known data is reached. The question provides five terms,




The correct answer is A. You flip a two-sided coin.
the fairest answer would be A. you flip a two-sided coin. a randomly generated number would not be fair, and your mom choosing would also not be fair, therefore the answer is You flip a two-sided coin.
