PLEASE HELP! 20 question

C

Step-by-step explanation:

So we have the following sequence:

-7, -3, 1, 5...

As given, the (direct) formula for any arithmetic sequence is:

Where aₙ is the value of the nth term, a₁ is the value of the first term, and d is the common difference.

From the sequence, we can see that the initial/first term is -7. Thus, a₁ is -7.

And we can see that each subsequent number if 4 greater than the previous one. Thus, the common difference is +4.

Therefore, plugging these into our equation, we have:

The answer is C.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
