<h3>Answer:</h3>

C)\ a_n=2a_{n-1}-1

<h3>Explanation:</h3>

You can try the choices to see which one works. The differences between an values double each time. They have the sequence 1, 2, 4, 8. So, you know that choices A) and D) do not work. They show the difference to be constant at 1 or 8. Since the differences are multiplied by 2, C) is a reasonable choice. Trying that, we find it describes the sequence perfectly:

a2 = 2·2 -1 = 3

a3 = 2·3 -1 = 5

a4 = 2·5 -1 = 9

a5 = 2·9 -1 = 17

___

Trying choice B on the last term, we have

... a5 = 3·a4 -3 = 3·9 -3 = <em>24 ≠ 17</em>

An equation is shown<br> X + 1 = 9x - 3<br> What is the solution?
STatiana [176]

Answer:

Step-by-step explanation: x + 1 = 9x - 3

x + 1 = 9x - 3

(minus x from both sides)

1 = 8x -3

(add 3 to both sides)

4 = 8x

(flip the equation)

8x = 4

(divide both sides by 8)

x = 4/8

x = 1/2 or 0.5
