Write an equation for the sequence whose third item is 27 and each item is 5 more than the previous.

9514 1404 393

Answer:

  an = 17 +5(n -1)

Step-by-step explanation:

The first term can be found by working backward from the third term:

  third term = 27

  second term = 22 . . . . subtract 5 from 3rd term

  first term = 17 . . . . . . . . subtract 5 from 2nd term

The generic term is given by the formula ...

  an = a1 + d(n -1) . . . . . a1 = first term; d = common difference

Here, we have a first term of 17 and a common difference of 5. So, the sequence terms are described by ...

  an = 17 +5(n -1)

Answer:

 an = 17 +5(n -1)

Step-by-step explanation:

Which statements are true about the ordered pair (−4, 0) and the system of equations?

{2x+y=−8
{x−y=−4


Select ALL correct answers.


The ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true.

The ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true.

The ordered pair (−4, 0) is a solution to the system because it makes both equations true.

The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.
