Would assume:
f(n + 1) = f(n) - 2
f(2) = f(1 + 1) = f(1) - 2 = 18 - 2 = 16
<span>f(3) = f(2 + 1) = f(2) - 2 = 16 - 2 = 14
</span>
<span>f(4) = f(3 + 1) = f(3) - 2 = 14 - 2 = 12
</span>
<span>f(5) = f(4 + 1) = f(4) - 2 = 12 - 2 = 10
</span>
f(5) = 10
Let me know if you need me to explain!
Answer:
a= 10/3
Step-by-step explanation:
multiply both sides by 2
get 6a +8 =28
subtract 8 from both sides
you get 6a=20
divide 6 both sides and 10/3.
Answer:
The Area = 28.26 or 28.27 depends if you round or not
5*5=25*3.14=78.5
3*3=9*3.14=28.26
---------
49.76
