Given the recursive formula, each terms is five time the previous one.
This means that:
is 5 times
, which means 
- in turn,
is 5 times
, so we have
. This means that 
- Finally,
So, substituting this back gives

In general, since you have
, each time you compute a new term you multiply by a factor of 5, so if
, you have

Answer:

Step-by-step explanation:
Given the following mathematical function;

<u>When x = 1</u>


<u>When x = 2</u>



<u>When x = 3</u>



<u>When x = 4</u>



<u>When x = 5</u>



AB is the longest side, so ∠C is the largest angle.
use law of cosine: 16²=9²+12²-2*9*12cosC
216cosC=81+144-256=-31
cosC=-0.14352
C≈98
