Find the 87th term of the arithmetic sequence 12, 0, -12
adelina 88 [10]

Answer:

a(87) = -590

Step-by-step explanation:

Notice how each term of this arithmetic sequence is equal to the sum of the previous term and the common difference, -12.

The general formula a(n) = a(1) + (n - 1)d becomes:

                                    a(n) = 12 - 7(n - 1)

and the 87th term        a(87) = 12 - 7(87 - 1), or

                                      a(87) = 12 - 7(86)

                                       a(87) = -590

Svet_ta [14]

The income of the amusement park is a function of the price of the ticket

The entry price that will result in no income is $24

<h3>How to determine the entry price that results in no income</h3>

The expression for the income is given as:

96x - 4x^2

When the income is 0, we have the following equation

96x - 4x^2 = 0

Factor out 4x

4x(24 - x) = 0

Split the equation

4x = 0 or 24 - x = 0

Solve for x

x = 0 or x = 24

This means that, the entry price that will result in no income is $24
