Answer : B.) f(x) =
The recursive formula f(x+1) = 4f(x)
Given : second term is 12 , so f(2) = 12
f(3) = 4f(2) = 4 * 12 = 48
f(4) = 4f(3) = 4*48 = 192
f(2) = 12 = 4* 3= 4*f(1). So f(1) = 3
f(1) =3 , f(2) = 12, f(3) = 48, f(4)=192.....
The sequence is Geometric
We use geometric sequence formula
, where 'a' is the first term and 'r' is the common ratio
a= 3 and r= 4
Explicit formula is

I am making this fake explanation for the points.. Got them, thanks!
Hi so I’m going to answer your problem which is “List three words or phrases used in real life that indicate positive numbers,” so let’s get right into it!
You can it as temperature too, today is 80+ degrees outside!
You can also use an the floors of which an elevator takes you in which direction it takes upwards or downwards like “take the elevator 4 floors up”
You can also use gas as a thing we use in real life, it also indicates numbers
Like gas is __ a gallon cheaper this week
You take 500,00,00 divided that by 400 and you get your answer 12,500
Hey there!!
(1) Both the angles sum up to be 180.
(2) Both the angles sum up to be 90
_________________
(1) 4x+5+8x-5=180
... 12x=180
... x= 180/12
... x = 15
________________
(2) 4z+3z+6=90
... 7z+6=90
... 7z=84
... z=84/7
... x=12
