<h3>Answer:</h3>

$\begin{cases}a_1 = 1500\\a_n = 140+a_{n-1}\end{cases}$

==============================

Explanation:

$a_1 = 1500$ means the first term is 1500, ie this is the first rent value.

To get the next term, we add on $140

$a_2 = 140+a_1 = 140+1500 = 1640$

and

$a_3= 140+a_2= 140+1640 = 1780$

and so on.

In general, the nth term $a_n$ is found by adding 140 to the term just before it $a_{n-1}$

So that's where $a_n = 140+a_{n-1}$ comes from.

harina [27]

Answer:

CD = 3

Step-by-step explanation:

Given 2 secants from an external point to the circle, then

CB × CA = CD × CE , that is

4 × (4 + 6.5) = CD × 14

4 × 10.5 = 14CD

42 = 14CD ( divide both sides by 14 )

CD = 3
