<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>

aleksklad [387]

Answer:

0.6

Step-by-step explanation:

Slope is the change in y divided by change in x.

x is weeks

y is height

We know plant grows 0.6 inches every week. This means per 1 week [change in x], the plant grows 0.6 inches [change in y]

Slope = 0.6/1 = 0.6

0.6 is the slope of the function
